Android vs iOS: which platform to build for first?

Over the past few years, the growth of mobile app development is simply astounding. And those who are into this field must be haunted by the million dollar question “ which platform (Android or iOS) should they select for their first app development?” Before answering this question, let’s take a look at some of the statistics. Gartner has conducted a study in 2016 and they found that 87.8% of smartphones sold worldwide were Android which is 3.1% higher than what it was one year ago. On the other hand, iOS’s market share is at 11.5%. This growth dominates other platforms significantly as Windows only accounted for 0.4% of all smartphones sold, for example.

Though Android is highly applauded in the global market, still iOS has its own loyal customers. Let’s take a look at some of the facts and figures that are linked with the iOS vs Android fight. This might help you to select one out of these two leading platforms.

Demographics: If you want to make an app, then at first, you need to consider you are your targeted audiences. Android concentrates upon having the masses but on the other hand, iOS is only for premium customers. That’s why iOS is popular in North America and Western Europe. Because these people are affluent, highly educated and thus, they love to spend money in-app purchasing and downloading. But if you are targeting a global market, then Android would be your prime choice. In Q3 2015, worldwide downloads on the Google Play Store were 90% higher than the App Store. This is because of the unprecedented growth of smartphone markets in countries like India, Indonesia, Vietnam, Central and East Europe, Africa, etc. These users have an adequate knowledge of price-quality ratio and they usually download apps ranging from tools to entertainment to communication categories. So, depending on your targeted market, you should wisely choose your platform.

Timeline: Timeline is another game-changing factor that you need to consider when you are planning to make an app. Making an iOS app is easier and faster and this is because you need to write less code in iOS. Generally, Android apps are written in Java which is a language that involves writing more code than Swift which is known as Apple’s official programming language. Another prime reason is Android is an open source platform. A lack of standardization means more devices, components, and software fragmentation to account for. On the other hand, Apple’s closed ecosystem means you need to develop only a few standardized devices and operating systems. If you want to make an Android app, then you need to make it compatible with all kinds of Android devices available in the market and truly speaking, this is quite time-consuming. Because the markets are crammed with thousands of Android devices which have a variety of screen sizes and OS versions. Since Apple creates all the hardware and software, there are fewer devices developers will have to build for.

Profitability and monetization: From a revenue standpoint, you need to select your platform prudently. When you are talking about profitability, then certainly iOS apps make more money than Android apps. A plethora of statistics has claimed that the App Store generates about 80% more revenue than the Google Play Store. In fact, Flurry recently found that Android apps generate only 24% of the revenue generated by iOS. This is because,

  • Apple users are wealthy and thus, they usually make in-app purchases and love to spend more on them.
  • Apple users are willingly paying for apps.
  • It is also true that shopping or e-commerce apps generate the most revenue.

On the other hand, the revenue of Android apps depends on advertising. So, if revenue is your top priority than the masses, then consider an iOS app. You can generate revenue through subscriptions, freemium models, or in-app purchases.

Though Apple is dominating in the revenue and profitability sector, still the revenue from Android apps is growing steadily. A plethora of studies has claimed that the Google Play Store consumer spend increased in Q1 2017, showing a strong growth of 40% year-over-year.

So, why there is a huge revenue gap between these two platforms? Because iOS provides customers with a chunk of paid apps and in-app purchases while on the other hand, Android has a high volume of advertising based apps.

Features: This is another prominent point that you need to consider while you are making a plan to develop an app. A market research shares that in comparison to android users, iOS users are 15% more likely to visit eCommerce stores. Not only this, but it is also noticed that 23% Apple users prefer purchases through their phone, in comparison to 17% in the case of Android. So, if you are planning to make a retail application, then go for iOS because the figures have already explained that they are ahead of the Android.

Releases and approval: As per the developer’s point of view, Android is always preferable specially when it comes to the release and approval process. For iOS, the release and approval process takes between 2 to 3 weeks, sometimes even longer if the app is rejected in the first time. On the other hand, Android apps generally take a day or two to get approved and updates can be pushed within an hour. So, it can be concluded that Android is more user-friendly. You just need to make a certificate, make sure you have the right keys in place for the push, and other services the app uses. Then upload it to the Google Play Store, and generally, within a few hours if it is accepted and then, you can release it. Google play store submission is less expensive and there are only a few rules when it comes to publishing.

Cost of development: This is a vital point that you should not overlook when you are planning to make an app. Though the cost depends on the number of features that you are planning to incorporate into your app, still Android apps are costlier. Because a large number of devices and OS versions on Android are available in the market. Not only that, for Android, you need to write everything on Java which is more verbose as compared to Swift or Objective-C. So, Android apps will require more time and resources, and thus incur higher costs.

When do you need to choose iOS first?

If you are planning to release your app in the developed countries or you are targeting high earning people, then iOS would be your prime choice. Not only that, iOS apps are less time-consuming and will give you more revenue. So, iOS is ideal for the start-ups who have limited resources and want to generate revenue as soon as possible?

When do you need to build an Android app first?

You should go for Android app first, if your target audience is squarely focused on Android, specially in developing nations or certain segments of urban environments. Also if you are planning to add a feature, which might not be easily accessible on iOS, you may choose to have Android application first. However, whatever the decision lands, you also need to keep in mind that due to the time it consumes in creating and developing, your project may get hampered or your developer may get irritated.

When to start with both the platforms?

If you want to start both the platforms at a time, then you should have a plenty of resources and should be well-established in this field. But if you are a novice, then you should choose one platform first for your app making. Else, it would be very difficult for you to survive in this steep competitive market.

Move to the next platform

Depending on your app’s requirement, features, demographics, etc. first choose one platform to release your app. Then, gradually you can enter another platform to get more users and profit. Consider the example of Instagram. They first started in iOS, later they release their Android version to gain more popularity.

Five years ago, Android only had a market share of 21.5%. But now, the things have changed drastically. With iOS bringing in more revenue and Android dominating market share, it would be a tough decision for you to decide a platform which is the right choice for your app.

Ultimately, your decision to build for iOS or Android first is going to come down to what works for your business. You should evaluate certain points before taking the final call.

  • The type of app that you are going to build
  • Your app monetization model (paid download, in-app purchasing, advertising, etc.)
  • Your targeted market region (North America, Europe, Asia, Global, etc.)
  • User demographics
  • Your final budget and the timeline of the project

Both Android and iOS have their own upsides and downsides. You need to evaluate all of them before making any conclusion. Hope the above information will give you an adequate knowledge and idea regarding which platform you need to choose for your first app development.

In today’s competitive world, the issue of mobile app usability is a big concern for all the businesses who want to establish their presence firmly in the market. Nowadays, the users are also very frenetic and demanding. They always expect a seamless and pristine mobile app experience. Right from onboarding to checkout, there should be absolutely no hitches. So, it can be concluded that usability plays an imperative role in enhancing the user experience.

Why should a customer use your app if they are unable to understand its UI or have faced difficulties while performing a task? They don’t even think twice before forsaking it. A plethora of statistics has claimed that nearly 88% of online user won’t return to a mobile app if they have faced usability issues within it. Near about 70% of online businesses fail to survive because of bad mobile app usability. So, you never overlook usability issues because they can tarnish your image and visibility.

What is the usability of the mobile application?

Most people have a scant knowledge regarding the usability and that’s why they often confuse UX design with usability and vice versa. The usability of the mobile application is a facet of UX which is integrated into the general relationship between the user and the product. UX depicts all aspects of the user’s perception of a mobile application, including usability. While on the other hand, the usability of the mobile application implies to the effectiveness, efficiency, and simplicity of the application.

It is true that mobile app usability encourages learnability. A successful mobile app should be intuitive and spontaneous so that the users can get familiar with the interface within a few minutes. If a user encounters an issue, a solution should be easily retrievable. You should use onboarding to guide users through the mobile app to enhance usability.

Mobile app usability requirement

  1. It should be very easy for the user to be familiar with the UI.
  2. It should be easy for the users to achieve their goals when they are using the application
  3. There should not be error and glitches in the app.

If your application is impeccable but the users are not comfortable they using the app, then everything will be in vain. In this article, we are going to discuss top 7 mobile app usability issues that are often overlooked by the app developers.

    • Usability of the platform: If you want to conquer mobile app usability issue, then all your apps should be designed in such a way that they should run in all the devices. The markets are crammed with various platforms like Android and iOS and even those two operating system has their own version of the software. If you are into an app development sector, then you can’t simply copy an iOS application for Android and vice versa. Because each operating system obeys different programming, design and interface considerations. For example, the navigation for each platform differs drastically. iOS, for example, does not have a “backup” button on your device like Android. For optimal usability of the application, your application should incorporate a clear and consistent way of returning to each screen. While making an application, always keep in mind that your users can interact with it intuitively. It would be a wise decision for you if you can plan your budget at the initial stage so that you can optimize your app for the most common Android and iOS smartphones.
    • Give value immediately: If you want new users to stay or return to your application, then you must ensure that they deserve the value from the beginning, preferably after the incorporation process. If you are unable to convince your customers to stay within the first week, then they will divert their focus and interest. And if this happened, then you will not only lose them forever but also you will meet a huge loss. These days, a plethora of applications are vying with each other to get user attention, so it is essential to ensure that your mobile application offers immediate value to the users. The good incorporation of users will not only reduce abandonment rates, but it can also help you in improving long-term success metrics, such as user retention and the value of the user’s life.
    • Simple navigation: Poor navigation is one of the prime issues that most of the users usually face while using mobile applications, particularly m-commerce app. When a customer downloads their application for the first time, they should understand how to navigate to complete their goal, whether they are booking a movie ticket or buying a product or searching for information. It would be good for you if your navigation should have as few barriers as possible. Many applications provide unique features, but often find difficulties while joining them in a way that makes sense to the users. You should properly use navigation so that your users do not get lost in a random page.
    • Clear and pithy content: Always make a simple and intriguing content when it is specially designed for mobile devices. You only need suitable and apt content that is essential for the user to complete a goal. This is particularly true for a purchase process. Consumers still need complete information to make their purchase, and withholding basic information will result in a lower conversion rate. You must adapt your content for mobile devices. Don’t try to copy the elaborate content from the web rather you should try to make pithy and concise content which will create enough interest among the users. Don’t give too much information in your mobile application because this will create a poor UX and your users may get frustrated while looking for a specific content. Make it easy for the users so that they can easily consume and understand the content with the least pinch and zoom. So, if you want to hold your users, then present the information in a clear and succinct way.
    • Minimize the number of steps: Always try to minimize the number of steps like the fewer pages, buttons, and fields to input data if you want to enhance the usability. Always check if there is any simpler way to complete an action so that the user can comfortably accomplish the goal. The fewer steps you include, the closer your users are to completing their goal. You make sure that all your users can store their billing and shipping information comfortably. Not only that, they can even add this information automatically to their orders, without having to re-add it each time. Always try to embrace your customers with an edit button during the checkout process. With the help of this button, they can quickly change their billing or shipping info if needed. If you are in a retail app or an m-commerce app, indubitably checking out is a frustrating endeavour. You have to type in your address, email address, confirm that you selected the right product, etc.- all while using a small screen. You can make this process facile and simple by creating an account with a Facebook login. Designing your app with a convenient guest checkout option will also encourage users to make more purchases in less amount of time. You can allow your users to save their personal information and credit/ debit card details makes the transaction process easy. Auto filled customer data not only improves mobile app usability but also enhances the customer experience. Because they can comfortably continue and enjoy their shopping without having to repeatedly add their information. So, in this way, you can improve your user experience and usability.
    • Reduce the displacement: It is true that the arrangement or prioritization of content improves the usability of a mobile application. Sometimes, moving down is inevitable and necessary but lateral displacement is something that you should avoid at any cost. If a user moves sideways, it usually hides valuable content. So, try to reduce side-scrolling to improve usability.
    • Go for landscape orientation: Many people who are into mobile app development often overlook or not prioritize horizontal orientation. A good mobile application should be designed both vertically and horizontally to adapt to optimal usability and UX. If you are making an application that contains video content, then don’t ignore horizontal orientation.

By employing A/B testing platforms you can test the usability of an application. With help of A/B testing, you to compare two or more variations of a particular app design or layout. For example, you can easily test the effectiveness of buttons and how they differ in driving conversions. Which design or layout converts more users? Stop guessing what users prefer in your mobile app, rather you should test to validate these assumptions.

In this steep competitive market, the success of a mobile app depends on how the users perceive or observe it. Usability helps you to understand what the users are thinking about your app when they are using it. So, don’t ignore usability because it will help you to convert a casual customer into a loyal and long-term customer.



An impeccably designed mobile app will certainly uplift your business and customer base and also helps you to firmly establish your presence in this steep competitive era. However, mobile app development comes across multiple development platforms and devices and this is truly challenging for the developers. Xamarin is one of the prime mobile app development technologies which offers a thinkable cross-platform solution that can easily work across multiple operating systems and devices. Based on Microsoft’s technology stack, Xamarin is a comparatively new technology in the field of mobile app development. But you must be astonished to know that it has a community of more than 1.4 million developers around the globe. Let’s dig a bit deeper and find out what is Xamarin and Why it is so popular?


Xamarin was created by the developers who developed Mono and it was introduced to the market in 2001. Initially, Xamarin was created as a commercial project until the company was attained by Microsoft in 2016. Very soon. Xamarin has become a popular cross-platform product for developing different mobile apps within the Microsoft ecosystem. Basically, Xamarin works on .NET and C# in order to produce original native Android and iOS apps with the same functions. It is a Microsoft-owned code language which uses cross-implementation of the Common Language Specification (CLS) and Common Language Infrastructure (CLI).

Let’s discuss some of the core advantages of using Xamarin for mobile app development.

Xamarin App DevelopmentAdvantages

Easy maintenance: Because of its cross-platform application, Xamarin makes maintenance and updates easier and simpler for the developers. You can simply do the changes or updates to the source file and they will be applied to both iOS and Android apps. So, it can be concluded that Xamarin saves both your time and money while keeps your apps updated.

A complete hardware support: Xamarin generally offers the use of a range of plug-ins and supporting APIs for cross-platform app development. This means you can really enjoy a native-level interaction with operating device hardware. So, with Xamarin mobile app development, you may face a little hardware compatibility issues as compared to others. While developing apps on the Xamarin platform, an app development company can stay relaxed because they need to build applications with commonly available device functionalities running seamlessly on assorted platforms. Moreover, Xamarin also allows the developers to link native libraries for designing apps with good-quality customizations.

API integration: Xamarin is the best cross-platform for mobile application development because it allows the developers to combine the same APIs and UI controls that they used for developing Android, iOS and Mac application in their respective platform-specific programming languages (Java, Swift, and Objective-C). Such binding competence allows the mobile users to install new features as early as possible when they are introduced into the device’s OS.

Shared app code: Why people are choosing Xamarin for cross-platform app development? The answer is this platform allows the developers to share the app code across multiple mobile platforms and OS. That’s why the popularity of Xamarin developer is increasing day by day and the companies are also hiring app developers who have a comprehensive knowledge of Xamarin. The important UI logics like input validation, web service calls, database interactions, back-end API integrations are all coded with C#. That’s why Xamarin has become a popular choice for cross-platform app development.


Native user experience and feel: Most of the app users generally prefer an application with a native design. Xamarin Studio (IDE) allows developers to code with C# which provides the benefits of a native user interface, access to device-specific features, and most importantly native app performance. Xamarin streamlines code sharing across multiple mobile operating systems such as Android, iOS and Windows Phone while reducing the product development lifecycle.

Rapid mobile application development (RMAD): RMAD is one of the prime benefits of Xamarin. And for this reason, today’s enterprises prefer cross-platform development over native development because it quickens the development processes at an affordable cost. Indubitably, Xamarin satisfies this requirement by the companies and also delivers native app-like look and feel, steady performance across platforms, and unparalleled user experience. Xamarin UI development generally uses forms libraries to make the process rapid, simple and smooth. This is the reason behind the popularity of Xamarin and that’s why it is considered as a business-friendly platform.

Benefits of C#: Xamarin uses a single language and i.e C# to create various apps for all mobile platforms. C# is an advanced, general-purpose, and type-safe programming language which is primarily used for the Windows platform. This is an object-oriented and a modernized version of C++. It enables even the basic data types to be treated as objects. Since this language has type-safety feature, hence by using this language you can prevent type errors which can result in flawed program behaviour. Since the app developers are using this language, hence they don’t have to involve boilerplate or verbose type annotations which enhances convenience while also avoiding erroneous program.

First app development cycle: The most amazing thing about Xamarin app development platform is that this platform contains reusable code 90% of which can be recycled for the development of apps on various platforms. The coding language is based on C# language and.Net libraries. For Xamarin, the app developers can easily reuse a portion of original Xamarin codes to create various apps across different platforms. Thus, it will help them to save a chunk of time and effort and also accelerates the pace of the app development cycle. Because of simplified code sharing across different OS, users have a shortened product development lifecycle.

Complete development ecosystem: Basically, Xamarin comes in one package with a complete development toolset. It has its own IDE (Xamarin Studio that is now replaced by Visual Studio), the platforms itself (Xamarin SDKs), testing (Xamarin Test Cloud), distribution and analytics (Hockeyapp and Xamarin.Insights) platforms. So, there is no need to invest in additional tools. Moreover, you don’t need to integrate the third-party apps in order to build, test, and deploy your Xamarin apps.

The above, we mentioned some of the core advantages of Xamarin. But like any other thing, Xamarin also has some downsides. Let’s take a look at some of the disadvantages of using Xamarin for cross-platform mobile application development.


Delayed support for the latest updates: It is impossible for third-party tools to provide the immediate support for the latest iOS and Android releases. It requires some time to implement all the changes effectively. Though Xamarin claims that it provides same-day support, still there are some delays.

Limited access to open source libraries: with native app development, you are free to use open source technologies extensively. But with Xamarin, you have to use only the components provided by the platform and some.Net open source resources.

Only a few experienced people are there: Xamarin community is much smaller than iOS and Android. So, it would be an arduous and challenging job for you to find an experienced and deft Xamarin developer. A plethora of statistics has claimed that the Xamarin community makes 10 per cent of the global mobile development society. Though the community is small, still the platform provides extensive support to the developers.

You need to know basic knowledge of native languages: You need to use Xamarin.iOS and Xamarin.Android to build mobile apps which may look and feel like native apps. This means you will still need to write a platform-specific layer of code. So, if you want to use the Xamarin platform, you need some knowledge of native technologies (Java/Kotlin for Android and Objective-C/Swift for iOS) Though with Xamarin.Forms, you don’t need this.

Not applicable for the apps with heavy graphics: one of the prime benefits of Xamarin is that you can share your code across the platforms. But you can only share the logic because UI code will be platform-specific. So, if you want to make game apps or complex animations, then it won’t be a prudent decision to use Xamarin. With a small amount of shared code, Xamarin becomes an unrealistic option.

App size is larger: Xamarin apps are larger than native ones depending on their intricacy and type. The size of a native app is half the size of a Xamarin app. Thus, you need to do additional optimization for your Xamarin apps to maintain the app size reasonably.

Inevitable software overheads: Since Xamarin app development creates a single app for all platforms, hence you can save time. But at the same time, it also involves in code linkage and referencing between target OS environments of different devices in use and.Net frameworks. It is true that this kind of effort is time-taken for initiation and downloads of the app.

Time: consuming nature of UI development: UI development on Xamarin platform is really a time-taken endeavour. Though Xamarin allows you to reuse maximum code across target device platforms, still it is very difficult to create a portable core UI. That ’s why Xamarin app developers are forced to do some portion of coding for the independent platform and this takes a huge time.

These are some advantages and disadvantages of using Xamarin for mobile app development and you should evaluate all these before making the final decision. Though most of the business houses prefer Xamarin because it lessens their time and cost by sharing the code and using a single technology stack. If you want to develop a pristine mobile application, then first consider your target audience and the purpose of the app and then, choose a platform for your application.

Hybrid mobile app developers

These days enterprises have started embracing technology like never before and that’s why the popularity of mobile apps both hybrid and native are growing hurriedly. Hybrid mobile applications have many resemblances with other applications and they get easily installed on your mobile devices. That’s why the users are showing their proximity to hybrid apps. Once you have installed these hybrid apps on your mobile, you can play games, engage your friends through social media sites, take photos, monitor your health, and can do much more things.

How are hybrid mobile apps built?

Hybrid mobile applications are built in a similar manner as websites. By combining various technologies like HTML, CSS, and JavaScript, the sagacious developers used to build hybrid apps. However, instead of targeting a mobile browser, hybrid applications generally target a WebView hosted inside a native container.

It is true that most of the hybrid mobile applications leverage Apache Cordova which is a platform that provides a consistent set of JavaScript APIs to access device capabilities through plug-ins. You should know that Apache Cordova initially started as a project named Phone Gap. These days, PhoneGap exists as a distribution of Apache Cordova which consists of many additional tools.

A popular example of Hybrid apps

Now, we are going to reveal some popular examples of hybrid apps and you must be astonished once you have heard these apps’ name.

  • Amazon Appstore
  • Uber
  • Twitter
  • Evernote
  • Gmail
  • Apple Appstore
  • Instagram
  • Feedly

Users point of view

From a user’s point of view, there should be no striking differences between a hybrid app and a native app. The customers or users really don’t care how an application is made rather they usually check whether the app can meet their expectations or not. It is the company which detects and decides which platforms are needed so that they can build a compelling application which can reach as many users as possible.

Developers point of view

Developers think slightly different way from the users. The developers prefer hybrid apps over the native apps because no developer wants to maintain multiple code bases willingly specially when given the option to support only one. So, in a nutshell, hybrid apps are the popular choices for the developers.

Let’s take a look at what choices are there for the hybrid app developers in 2018 and in upcoming years?

Flutter: Flutter is an intriguing framework for Dart which focuses on the concept of Widgets. Though it is in beta stage and the learning resources are also limited, still, it is highly recommendable for those who are desperately looking for a Dart-based solution. This framework supports a variety of expected mobile development features like hot reloading, device API access, performance profiling, and many more. Flutter is also supported by desktop embedded applications for macOS and Linux. In order to encourage the companies to adopt Flutter, Google is creating a chunk of Flutter content and is also promoting and speaking about it. It is true that Flutter prospect is not very high in these days, but if you can learn this framework and can become an expert of it, then in future, you will get a plethora of benefits when it will become popular. Flutter is already a part of Google’s new Fuschia operating system project, so you can expect a scintillating future of Flutter in the upcoming days. At present, the downside of Flutter is the lack of a templating language. People who have an adequate knowledge are using XML based templates and till now, this is the most comfortable way to develop views.

Fuse: Fuse could be an ultimate choice for those who want to create something new. Fuse has many resemblances with Flutter. Though it uses OpenGL to create native mobile apps with JavaScript, still it lacks Android/iOS UI components. Generally, Fuse comes with Fuse Studio and a desktop tool which can be used to assist in the creation of Fuse applications. Many beginners find Fuse studio very useful to develop the applications. Recently, Fuse has gone entirely open source with no paid business model over at Fuse Open. Now, you can easily get access to all of the previously paid plugins, themes, and features without any hassle. Indubitably, this is a great community, but because of slow internal development, it has not yet become successful.


Ionic 4: You should know that Ionic framework is a complete open-source SDK for hybrid mobile application development. Built on top of Angular.js and Apache Cordova, Ionic provides tools and services for developing hybrid mobile apps using Web technologies like CSS, HTML5, and Sass. Ionic primarily uses the WebView in order to display content, with the WKWebView now shipping as standard. Ionic applications on iOS saw the substantial performance and stability improvements as compared to the previous UIWebView. Ionic is no longer dependent on Angular. This is because of the higher adoption with the ability to mix and match technology stacks. A prime strength of Ionic is the documentation. A chunk of examples and subsequent preview inside of the browser allows for an easier learning curve. The Ionic CLI is easy to use and it is integrated with Cordova tightly. It means you can easily build an application for production or running it on a device. Ionic is a great choice who want to create both mobile and web version of their app.

Weex: This framework is developed by Alibaba and recently, it is picked up by the Apache Incubator which uses Vue.js or Rax to create native mobile applications. Weex has a playground that can be used to test or develop a prototype. Though it has an official Gitter Chanel, currently only one Chinese room is available. Since most of the examples and plugins are in Chinese, thus, people are not willingly adopting this framework. And, this is the main limitation of this framework.

React native: This is the most applauded and popular framework for hybrid application development. Reactive Native has a fairly large community as compared to other frameworks. Though this framework is not advised for the novice developers, the huge community encourages them to dive in and explore the framework. This framework is used by some Tech giants like Facebook, Instagram, Airbnb, and many more. This is basically a JavaScript framework which is built with React. Instead of targeting the browser, it targets mobile platforms with different UI elements. You can use React Native to develop mobile applications for both iOS and Android platforms. React Native also supports Hot Reloading and thus, you can make development in a quicker way because you don’t need to wait for the application to restart after each change. This saves a chunk of time specially when you are making many small changes. The prime disadvantage of this framework is that version 1.x is not still available with it.

NativeScript: NativeScript is another awesome open-source framework which you can use for developing apps on both iOS and Android platforms. Originally, created by Progress, NativeScript apps are built using JavaScript, or by using any language that transpiles to JavaScript, such as TypeScript. NativeScript supports both Angular and Vue frameworks via a community-developed plugin. Recently, NativeScript has released version 4.0 which helps developers to create cross-platform native applications. Mobile applications that are built with the NativeScript result in fully native apps, which use the same APIs as if they were developed in Xcode or Android Studio.

      • Native APIS: You can easily access Native APIs. It has the ability to take Swift and Java code from the Android/iOS documentation. By doing some small changes, you can comfortably access those features. In Native Script, most of the time you can use an already created third party plugin which implements the native functionality for you.
      • Debugging: As a developer, very often you need to give your Chrome developers tools in order to debug a running application. But with NativeScript, you can use this for both iOS and Android. Using the debugger, you can do many things like inspecting errors, changing element properties, etc.
      • NativeScript Sidekick: Tooling and the surrounding ecosystem are imperative specially when you have a large team.  NativeScript Sidekick which provides a GUI to the NativeScript CLI with templates, plugins, and many more things. If you don’t want to remember every CLI command for your favourite tools, then Sidekick will help you to accomplish your job comfortably.
      • NativeScript Playground: NativeScript Playground is suitable if you want to boot up a project from within the web browser. This is great if you want to share smaller examples or want to create prototypes. You can easily access the application by downloading the NativeScript Playground companion application on iOS and Android and then, can scan QR code.
    • NativeScript-Vue: With NativeScript-Vue, you can get the power of NativeScript, but with the Vue rendering engine. If you want to practice your Vue skills, or if you have already written a lot of Vue but want a mobile application, then NativeScript-Vue is the first place from where you can start. You can access many features with plugins very simply. Code sharing is also possible with the NativeScript-Vue-web pack-template.

If you are planning to create a mobile application, then go for hybrid apps because they are the perfect solution to your problems. Moreover, hybrid app development is growing very rapidly and in 2018, a hybrid app developer will be boasted with a plethora of options. So, depending on your requirement, you can handpick any application framework which can happily meet all your demands and requirements.

Agile vs Waterfall, What methodology is the perfect fit for your project ?

In this digital ecosystem, the markets are crammed with mobile apps and smartphones. Smartphones and apps have emerged themselves as your real friend in need and playing a decisive part in your life by simplifying your daily tasks. Thus, it becomes a challenging job for the app developers to develop an app having a long lifespan. Moreover, these days, customers are also becoming very fussy and demanding. So, it is mandatory for a mobile app development company to adopt the latest trends of the market if they want to flourish in this competitive era.

These days, most of the companies are embracing the agile methodology which is most efficiently used by mobile and software development companies. This technology is quite helpful in streamlining the most complex and intricated development process and makes it faster and easier.

What is agile technology?

Agile technology is a process in which the entire development process is segregated into different development cycles. So, basically, this method divides an entire task into different subtasks and each subtask thus becomes a separate module for the development team. In the agile development process, an entire project becomes an integration of different modules or jobs. Then, each module is assigned to a dedicated and sagacious person and acts like an independent project.

Why is agile technology required for a mobile app development process?

It is true that a mobile app development process is a very tedious and formidable job. It needs assistance from the experienced and pedantic person who has a vast knowledge of app development. Moreover, in a mobile app development process, you need to discuss a lot of things with your customers, project manager, and your development team to understand in detail of the projects and to identify the key objectives. If you want to make your project successful, then you need to wisely allocate the tasks and there should be a strong and coherent communication between the team and the customer throughout the process. Handling different parts of the project and the team becomes a difficult task for the project managers. Here, by choosing agile technology for the development part, you will certainly take a wise move.

Agile technology not only saves a chunk of time for you but it also ensures that every process of the development is executed properly. Moreover, agile technology also ensures that the customers and the development team are also well coordinated during the app development process.

Barry Boehm and Richard Turner provide a list of procedures that are essential to agile development in their 2003 book, Balancing agility and discipline: a guide for the perplexed.

According to them, some of the characteristics of agile development are,

1. Simple design

2. Ability to release in short period of time

3. Anticipating the need to for changes

4. Team coordination is excellent

5. Pair programming and testing

6. Always welcomes the changes and uses them for the betterment

What are the benefits of using agile development method?

Agile is a proven and effective model for software development. A plethora of companies have already adopted this technology and are getting benefited by this advanced method. Agile not only enhances the quality of your project but it also saves million dollars for you.

Let’s take a look some of the key advantages of the agile development process.

1. More productivity: In an agile development process, the entire work is divided into smaller chunks and the deliverables are completed in shorter iterations. This will certainly minimize the chance that a programmer gets too far off track on a project, and when some problems occur, they can be identified easily and solved quickly. Everything in agile development is very simple from team processes like Scrum to development practices can be managed easily. Since everything is managed smoothly in an agile process, thus it automatically enhances productivity.

2. High quality throughout the process: Agile process always encourages completion of work in small batches. Since the entire work is divided into parts, hence you can easily test those small units and if there is any error or bug, you can fix it quickly without wasting time. So, the technical issues or bugs are minimum with an agile process and thus, it maintains the quality of work throughout the process.

3. Commitment and accountability: Commitment is another reason behind the popularity of agile development. Because agile process always encourages for shorter commitments with goals. If you ask your team to commit to a set of deliverables 18 months in advance with proper dates, functionality and a development budget, then this is certainly an unrealistic move. Rather you should ask them to give commitments for short-term periods with proper planning, goals, and budget. The developers will have fewer issues in committing to shorter chunks of time and thus, they can give a proper estimation of their work with a full accuracy.

4. Clearer communication: Agile always encourages clearer and more frequent communication between all the members who are involved in the development process. Since in agile development process, every member needs to communicate very frequently, this will strengthen the relationship between every team member and also improves the clarity of the project.

5. Cost saving and transparency: In the agile development process, a project manager is required only for longer-running efforts. Since the whole work is divided into many parts, you don’t require a project manager to manage all those things. In this way, you can save a lot of money. Moreover, agile teams are transparent with their progress which means there is no need for middle managers to collect and check the status of the project. Here, you can easily calculate and check your progress by clicking on a button for teams using a software management tool like Jira. This will help minimize your cost and helps you to utilize your money in other ways.

6. Continuous improvement: Agile development is a retrospective process. The team continuously do the changes if they have found an issue so that the whole process can work in a better way. Agile also encourages the team to go for a more automating process which they previously operated manually like testing and deployments. Since now the organizations are more relying on automation, hence they can easily meet their timeline and this is very effective for a lean team. Once most of the operations are automated, then a move to cloud hosting can also save on both capital and operational expenditures.


Waterfall technology

The waterfall is a traditional and linear method for software development. This technology goes through a number of sequential phases. These phases are

1. Stockpile all the requirements in a documented file

2. Design

3. Code

4. Unit test

5. Perform system testing

6. Perform user acceptance testing (UAT)

7. Fixes an issue

8. Deliver the final and finished product

In a waterfall project, every phase represents a distinct stage of software development and you need to finish each stage before going to the next one.

Waterfall project has many upsides and downsides. Let’s take a look at them.

Pros of a waterfall project

1. Since both the developers and customers commit on what will be delivered early in the development cycle, hence you can make all the plan and design in a straightforward way.

2. As the full scope of work is known already, so you can easily measure the progress of the project.

3. The team members don’t need to be co-located, although the risks can be managed easily.

4. Except for reviews, approvals, status meetings, etc., a customer presence is not mandatory after the requirement phase.

5. When you need to manage a large-scale designed project or where more analysis is required or where the impact of downstream changes to design is very high, waterfall method is the best suitable approach.

Some downsides of waterfall project

1. A waterfall project is committed at the early stage of development based on some assumptions. This can create a havoc problem because most of the things are assumed in advance.

2. In a waterfall project, working software isn’t produced until the end of the project, so you never really know where you are on a waterfall project.

3. The risk is always higher with a waterfall project. You can get technical risks because you are not allowed to test your design until late in the project. And simultaneously, you have got product risk because you don’t have an idea regarding your accuracy of building the product until it’s too late to make any changes.

4. In a waterfall project, testing is done at the end of the development phase. Sometimes a project doesn’t have money for testing because they have spent a chunk of money in designing and development. Very often, they cut the testing process and thus, quality suffers.

Agile approach

Instead of treating all these issues in fixed stages, agile approach believes that these are continuous activities. An agile approach can easily solve all these issues by the following ways.

1. Quality improves in an agile approach because testing starts from day one. Thus, you will get the best quality for your product with an agile method.

2. Visibility improves with an agile method because you are 1/2 way through the project when you have built 1/2 the features.

3. The risk is always low because you are getting feedback early and you can incorporate all the necessary changes from the very beginning.

4. Customers are satisfied because they can make any change without paying an exorbitant amount. At the end of the project, they always get the best product because everything is done part by part in an agile method.

Agile and waterfall are very different from each other and they have their own upsides and downsides. You can apply waterfall method virtually to any type of IT project but agile requires some specific conditions. Thus, you can’t apply agile to any project specially large-scale projects are not at all suitable for an agile approach. So, depending on your project requirement, customer demand, and team size you can choose any of these methods which will help you to accomplish your project in a hassle-free way.

To infiltrate the market, every business wants to develop its own app and create its own market. This has been made possible due to the latest trends in the mobile application development. There is no doubt that the mobile users are the ideal targets as they can be reached prominently using such apps. Truth be told, the companies, which are still lagging behind using the age-old online marketing strategies, will become obsolete if they do not upgrade themselves to the app-based world right away.

Top Trends To Follow In 2018

The businesses are stepping up to create a better user interface for the smartphone users. The unique platform incorporated in the apps make a permanent effect on the users’ mind hence proves to be very useful for the business to stay alive in the competition. Below is the list of top trends in the world of mobile application development that will rule in 2018.

Internet Of Things (IoT)

As per the indications from Forbes, IoT is going to be the next big thing. The emergence of Artificial Intelligence will be the prime factor this year that will increase the understanding of IoT. As per the Vice President of Watson IoT Consumer Business, IBM, Bret Greenstein, IoT will be the ultimate bridge between the tools we use online every day.

The evolution of IoT environment with the advent of natural processing of language, deep leaning, image recognition, etc will enable the industries to create and enjoy the integrated experience for a better understanding and interaction with the people.

In 2017, the evaluation of IoT was $170.57 billion which is expected to rise to $561.04 billion by the end of 2020. The Compound Annual Growth Rate per year is impressively 26.9%. The B2B segments in IoT sector will along generate more than $300 Billion by 2020. The number may vary in the next three years but the trend will remain the same. IoT is the next big thing in mobile app development. The evolving market will require the customized IoT applications for the business. The developers will be on demand.

Internet Of Things

Augmented Reality

The advent and availability of augmented reality in the year 2017 have opened new ways for the development of new things. Google and Apple have taken AR to a new level and made it accessible for the users. Apple will launch its own ARKit whereas Google is ready to launch ARCode in the recent times. These two companies have the highest number of smartphone users in terms of user interface. It means that the development and use of AR apps will increase a lot. The users will be able to experience AR and this will be a great advantage for the app developers to come with their own AR apps.


Wearable tech

Everyone now craves to own a smartwatch. The users can now easily afford a smartwatch as the year 2018 will earmark the development of smartwatches and other wearable devices. These devices will remain connected to the smartphone and will offer exceptional features. The wearable technology will still require some assistance from the mobile applications though.

Instant Applications

This is a new concept that will be introduced in the year 2018 and further where the user will not have to download an app to find out what it does and how usable it is. The app store will provide a simple platform where the users can easily use the app as a trial in order to understand its functionality and easement. If convinced, the user will proceed to download it in his or her phone. It will solve the storage issues in the smartphones. The apps like Wish, Viki, Periscope, Buzzfeed, etc will take the initiative and become the pioneers in this field.

Artificial Intelligence and Machine Learning

The machine learning technologies will initiate and facilitate the cognitive system for engaging, reasoning and learning. The devices will use AI to learn more about the user trends, habits and other personal aspects so as to deliver the right recommendations or perform a work. Machine learning is a typical data analysis practice that enables a user to create a mechanical analytical model. The machine will learn from the data fed and the tasks will get automated with a minimum requirement of human intervention to do the things.

Machine learning has a huge prospect in the IT, logistics, healthcare, energy, education, and other industries. The introduction of AI-based apps will offer a unique user interface that will have recommendation engines for a personalized experience. The behavioral targeting feature of the recent apps will make it easier for the users to find what they want without giving any command.

AI is also revolutionizing the user experience by introducing chatbots. This is a typical AI-driven tool that enables a business to answer the questions and queries of a user without using any human intervention.

Artificial Intelligence

Cloud computing will be the thing

The year 2018 will witness a surge in use of cloud computing via the applications. The mobile applications will come with a new feature where the users can create a backup in a cloud storage platform. It will become a lot easier to store data and a user can save valuable space in their smartphones. The heavier tasks can be easily done via the access to the cloud storage from the mobile phones. This feature will require a powerful network provider who can stream data without any hindrance. It might be a drawback for the third world countries where the networks are not that powerful. The feature will increase the security of the mobile applications and allow a user to enjoy a large volume of storage. It is expected that the cloud-based mobile apps will hit a 22% CAGR and increase its worth to $178 Billion from $146 Billion last year.

Mobile payments

The mobile payment apps are also on the rise. The majority of the smartphone users find it easier to pay via the mobile apps. It is easier to handle accounts. The payment processes via the mobile apps are becoming faster and more secure. Google is going to take a step ahead and introduce an online payment platform ‘Google Pay’ that can be controlled by any Google device. The technology for Near Field Communication (NFC) is being used in the smartphones. NFC chips are introduced in the motherboard of the devices which can be accessed by the shop terminals. The total amount of the shopping will be directly deducted from your account without any hassle.

Mobile Banking

Mobile banking past 5 years

The poll and survey suggest how the users are enjoying a peace of mind using mobile payment methods to checkout from a store easily. As per the predictions from the IT Pro Portal, the mobile payment users will increase by 90% within the year 2020.



Accelerated Mobile Pages (AMP) is the unique project from Google in collaboration with Twitter where a transformation of the web pages into the mobile version allows a user to load and see the website content faster and more efficiently. The user will not have to wait for long as the AMP will load way faster than the original website.

Mobile Security and BYOD concept

The popularity of BYOD or Bring Your Own Device to the office for work-related solutions can hamper the integrity of the system-based apps. In order to maintain a proper security of the enterprise-based mobile applications, the security measures will tighten. The app developers are making the security features of the enterprise apps more stringent and fortified so that the personal device cannot harm the integrity of the system.

The corporate interface can now be safely and easily accessible by the users via their own devices. The advent of cloud technology also mandates the fortification of the business apps so that the sensitive information can remain safer in the employee’s device.

Cross Platform Native App development

The necessity of industry-based applications will increase where all the entities linked to the goods and services will be included on a single platform. The global market for the application development will increase with the demand of cross-platform ones. It is more cost-effective for both B2B and B2C enterprises. The cross-platform can be converged and accessed from different devices.

The developers will not have to spend more time in developing apps for multiple platforms. The hybrid development concept will allow the formulation of a single app that can be run by any device using a single coding language like Xamarin.

Light version of heavy apps

The lighter version of heavy apps will also emerge as a new trend. These apps will require a very small space in the internal memory to install. The usage of these apps will also not drain your battery or your mobile data.
Enterprise applications

The new era of enterprise applications is here. The apps will provide a revenue stream from the users. It can be developed in any field such as healthcare, telecom, software, financial services, etc. The developed app will be catered to the users for a particular set of service.

The enterprise apps also provide a great solution for inter-department communication in the big companies. Skype, HipChat, WorkPlace from Facebook, Slack, etc are the few examples. 2018 will witness a rise in such apps.

Gesture control and animations

The latest fad of the mobile application world is in-app gesture controls. The gesture-driven UI is less cluttered and easy to use. The applications will offer a unique user interface where very fewer buttons will be there on the screen. The rest will be controlled by the hand gestures of the user. These apps will not have a complex interface and can be easily handled by simplest devices having a particular set of hardware features.

The mobile apps will become more personalized and user-specific. The use of intelligent platforms will ensure that the user can enjoy an individualistic experience. The cloud-based apps will offer more space to load and store files. The 5G trial test will be done shortly and every user will find a high-speed network connection around the world. The advent of intricate yet simple apps will also make the lives easier and convenient for the users. These are the few trends to look out in 2018.

Nowadays, a mobile app is the utmost weapon by which a company can fascinate new customers and simultaneously also maintain their regular customers. With these mobile apps, most of the people are now accessing their desired information, finding products and services and even making purchases. According to the statistics, as of 2015, there are near about 4.43 billion mobile users throughout the world and number is likely to reach to 5.07 billion by 2019. Apart from attracting new customers, a well-designed and coherent mobile application will also increase the conversion rate. So, it can be concluded that a mobile application acts as a catalyst which can satisfactorily increase the customer base of a company.

By seeing the growing demand for mobile applications, many companies and enterprises are showing their propensity in designing their own apps which can boost their business ten times. Though apps are very beneficial for the users it is also true that the app development process is not at all a simple endeavor, a lot of intricacies are hidden in every step of development. Hence, a company needs to employ some top mobile app developers who can successfully accomplish the whole development process.
If you are planning to develop an app, then you also need to invest a chunk of money because in every phase of development process you need to spend a lot of money. Before you proceed to the app development process, let’s sort out some queries that are roaming in your mind.

The first question that should be wandering in your mind is what is mobile application development?

A mobile application development is a process in which a developer or programmer needs to write various codes using different languages like HTML, CSS, JavaScript for different devices. When a developer builds an application for a device, it means that code is only acceptable for that device. For example, the code that is used to write for an Android device should not well-suited for an iOS device. So, for an iOS device, a developer needs to write separate code so that the software can run smoothly on that device.

While you are planning to design a mobile app, you need to remember certain points. Here, we are mentioning some points that you should think before developing your app.

1. Platform: This is an imperative parameter and it plays a significant role when you are planning to develop your app. Before choosing the platforms for your app, you need to decide the location where you want to launch your application and your target customer If you are planning to launch your application in the countries like the USA, then keep the focus on iOS platform. Similarly, you can choose Android platform which is being preferred in the countries like India. Once you decide the platform, you will get more coverage and audience base for your application.

2. Native, web-based app or hybrid app: In a native app, you need to design the same app for multiple times so that it can run on various OS platforms. Usually, native apps perform accordingly device’s features; hence, companies are often showing their interest in native apps. While on the other hand, web-based apps (HTML5, CSS3, JavaScript) are cheaper and faster because you need to build only one app which can successfully run on different platforms. There is also another app which is known as a hybrid app that can be designed by combining both native and wave-based apps. Every app has their own pros and cons. Native applications are costlier and time-consuming, but they provide the faster user experience. On the other hand, hybrid apps are less costly and less time-consuming. So, you need to choose that particular app which satisfactorily meets all your needs.

3. Backend: This is another important thing that you need consider as most of the application today are API driven. At the very same time, not all applications that are developed by you won’t require a customize backend programming and can easily connect to other mobiles using APIs. So, you can proceed comfortably with your local database as such applications don’t require the support of the backend.

4. Target audience: Before developing your app, wisely identify your target audience and if required, do a thorough research on that. Your aim is to serve the people in a better way so that you can generate good businesses. Never miss the important factors like locality in which your application will going to be launched, age group, any other preferences, etc. If your application deals with the buying and selling, then it should be very professional in terms of look and should meet all the standards of buying and selling.

5. User interface and design: If you ignore the UI/UX and design, then your application will not get a good response from the audiences. The UI/UX design is the most significant pixel because it decides the success of your application. For this, you need to clearly understand the difference between user interface and User experience. A good application always possesses both these traits. While designing your app, make sure that your developer and designers have an in-depth knowledge of both user interface and user experience. That’s why app development part is the most crucial part because your app’s success depends on it. A plethora of statistics has also claimed that 99% people don’t return to the applications because they feel that the apps are not compelling and user-friendly.

6. Do a thorough competitor analysis: Before launching your app, do an in-depth analysis of your competitors. Most of the people ignore this step and hence these days, the app stores are flooded with thousands of apps of the same category and they are vying with each other to grab the attention of the customers. If you want your application to become successful then offer something that is not available in other application before. In early 2012 there were only a few applications and the market the market was also open. But over the past few years, the mobile apps are growing hurriedly and very often, you can see that multiple applications parallel to one development idea. So, go for some unique idea which can grab the attention of the customers.


7. Test your app before it launches in the market: Your application should be easy to understand, user-friendly, and will always give the best performance. Thus, it is very imperative to test your mobile application before you are planning to launch it in the market. The testing will give you an idea how your audience will react when they will see or use for the application. A thorough testing will allow you to iron out any nooks and crannies before it reaches the mass market. First, you go for alpha testing and then, at the second phase, you can go for beta testing. You may recruit some efficient and deft beta testers and try to improvise everything you can as per the observations. These days, the markets are crammed with many testing tools which will help you to organize the beta testing.

8. Plan for multiple releases: This could be a great idea if you want to keep your users engaged with your application. Always plan for multiple releases after releasing the initial version of your app. A plethora of studies have claimed that many users will re-engage with your application when they found new features are incorporated into the app. But be careful not to release too often, lest users feel bombarded. A gap of 2-3 months between the releases will instigate the interests of your users and will keep them engaged over a longer period of time.

9. Plan your budget in advance: Mobile app development is indubitably a costly endeavor. You need to spend a humungous amount of money in every step of your application including the development part. Planning your budget in an advance and allocating it among every step is very important if you want success in this steep competitive era. It would be better if you hire someone who can keep a strict eye on every step to ensure that your budget will remain constant until the end of the process.

10. Plan to analyse: The final step of your app development process is to measure success. With a morass of potential features, devices, platforms and technologies, success can be very challenging to define and it can affect your strategy. So, ask the following questions firmly.

  • Will your app increase your customer base and retention?
  • Will it enhance your brand value and loyalty?
  • Will it decrease or lessen your cost?
  • Will it enhance your revenue?
  • How many people do you want to use your app?
  • How are you planning to integrate social media with your app?
  • How will you integrate it with your existing analytics tools to get a better insight?

11. Make a robust app marketing strategy: Creating a buzz is very important if you want that your app will reach the zenith of success. You need to make and execute your app marketing strategy at the appropriate time. Most of the mobile app developers don’t get success because they don’t make a strong app marketing and execution process. Generally, the developers should start app marketing at least before 2-3 weeks before launching to let the users know. If you want to get an overwhelming response to your app, then creating a buzz is very pertinent.

The app development process is always a tedious job. You need to spend a lot of time in researching, developing, testing, marketing processes, etc. to make your app successful. The above we mentioned some traits that you must consider while developing a mobile application if you want to generate a good business from it.

Mobile metrics

A compelling and feature-rich mobile app is a power in your hand which will help you to reach over 6 billion people around the world. Be it start-ups or large companies, every organization aims its application to take place in the customer’s’ devices. In this competitive era, developing a mobile app will not help you to establish your presence strongly in the market, at the same time, you need to be proficient in analytics. This analytics will help you to evaluate how your app is doing? Or what are the areas you need to improve?

Here, we are mentioning a list of mobile app metrics and mobile app KPIs which will help you to measure the impact of the hard work that you have put in developing some enchanting mobile apps.

1. Cost per acquisition(CPA): Basically, cost per acquisition is the cost of acquiring or gaining a new customer for your online business. This is generally one type of advertising revenue models where a publisher gets paid for a specified completed action. CPA usually measures how much amount you need to spend to get an active user or subscriber. CPA is calculated on a monthly, quarterly or annual basis.

CPA=Total cost of campaign/ number of acquisitions

Why do you need to track CPA?

1. This will attune your campaigns in real time
2. Helps you in calculating return on investment
3. Helps you to measure the effectiveness of ad spending

2. Lifetime Value(LTV): Lifetime value (LTV) is basically how much total revenue you can generate from a user before he or she stops using your app. This will help you to calculate how long you need to retain your users so that you can make a good profit from them. Moreover, LTV will also help you to estimate how much revenue your app will make in the future. LTV will help you to understand whether you are spending your marketing budget prudently and attracting the right crowd or not, based on the value they bring. LTV usually goes hand in hand with CPA.

Why should you track LTV?

1. To predict the profitability of your app in future.
2. To estimate the cost of marketing
3. To analyse the loyalty of your users

3. Retention rate: This portion of app metrics will help you to know what percentage of users you are retaining. You will also able to see how many customers you are losing to churn. Basically, the retention rate is the percentage of users who usually stay with an app for a given period of time after the completion of the installation process. Generally, long-time users are more likely to spend money on your app, they will purchase your other products and will do a word-of-mouth publicity for you. By calculating the retention rate formula, you can check the performance of your app.

RR= ((E-N)/S)X 100

E= number of customers at the end of the period
N= number of new customers that you have gained during the period
S= number of customers at the start of the period

Why do you need RR?

1. Will help you to estimate the performance of your app
2. Will help you to identify the traffic sources
3. To identify you the most valuable customers

4. Churn rate(CR): This metrics is exactly opposite to retention rate. This is the percentage of users who used to uninstall your app within a given period of time for a specific reason. Localytics did a survey on this topic and they found that in general, 58% of users churn in the first month with the average reaching 75% by the third month. The lower CR will increase the performance of your app.

CR= 1-retention rate (RR)

Why do you need to check CR?

1. To enhance the performance of your app
2. To identify the weak areas of your app
3. To make a better app marketing strategy

5. Daily active users(DAU): Depending on the usability of an app and the frequency of sessions, mobile app users can be divided into three groups and they are daily users, weekly users, and monthly users. DAU is the number of active users per day. This refers to each user who has at least one session per day. It is very imperative for the app marketers to bring back those users who left the application after the initial sign-up process. You must send push-notifications or try to encourage them with incentives so that they can use the app again.

Why do you need to track DAU?

1. To monitor the growth of your app
2. To measure the retention rate and user engagement for your app.

6. Monthly Active Users (MAU): MAU usually tells you the unique number of customers who used your app for a specific month. The customers who have at least one session in a 30-day period are called monthly active users. Calculating MAU will help you to identify the engagement of users who return to your app and interact with it on a monthly basis. Every brand or company has their own set of criteria to calculate MAU. As per Statista report, in April 2017, Facebook Messenger had 1.2 billion mobile MAU worldwide.

Why is MAU calculation important?

1. To check the monthly growth of your app
2. To measure the success rate of an app


7.App Stickiness: Stickiness is the ratio of daily active users (DAU) to monthly active users.

Stickiness ratio= Daily active users (DAU)/ Monthly active users (MAU)

This metrics actually determines the consistency of user engagement with an app. Though a lot of users download an app, still after some time, they left the app. To cope up with this issue and increase the stickiness ratio, it is very important to re-engage, incentivize, and give some lucrative offers to the users so that they can come back to the app. Hence, every app should be sticky so that users would love to come back to it again and again.

Why do you need to track Stickiness?
1. To improve your conversion rate
2. To identify the loyal customers

8. App session length: This will help you to understand the behaviour of your users. App session length is basically how long a user actively uses your app from start to end. Opera Mediaworks claimed that the average user spends about 5 minutes in an app, and the duration of sessions tends to increase with each passing year.

Why should you track session length?

1. To improve the UX of your app
2. To check the user engagement

9. Click Through Rate (CTR): CTR conveys the ratio of clicks to impressions. It is generally used to determine the success of a particular ad campaign. A high CTR will automatically reduce your cost.

CTR=(Clicks/Impressions)X 100

What is the importance of CTR?

1. To optimize the performance of your ad campaign
2. To measure the success of an ad

10. Return on investment (ROI): Basically, return on investment is the profit that you have earned from a marketing campaign compared to its cost. Measuring ROI is a daunting task for the marketers. At first, you need to calculate your CPA and LTV and then, make up an overall cost analysis. For example, if you want the ROI of a promotional email campaign that you have sent, then, at first, you need to tally the cost associated with building and sending that campaign (marketing promotions on various platforms, design costs, etc.). Now, you need to enter that cost into the formula below along with the revenue gained from sending that campaign.

ROI= (Gain-investment cost)/ investment cost

The importance of ROI
1. To estimate the marketing expenditures
2. To access the feasibility of a mobile campaign

11. Funnel tracking: Funnel depicts the sequence of your user flow from acquisition to conversion. Moreover, funnel gives valuable insights on how your customers behave at various stages of the funnel. It helps you to identify in which areas your users have some issues and eventually they drop off. Now, the job role of a campaign manager is to optimize the marketing strategy and tackle all the issues wisely.

The importance of Funnel tracking

1. To optimize your marketing strategy
2. To get a deeper insight of your user’s behaviour
3. To monitor your campaign

12. Virality: Word of mouth is very important in this competitive era. It accentuates your app growth and profitability. Virality measures how many new users an average user can bring to your app. From the very beginning, these users tend to be more active and loyal to your app. If you want to make an app viral, then you need to spread it on social media. Clicks, likes, and shares are virality metrics when you are planning for an app promotion.

How will virality help you?

1. This will help you to know how many people are using, liking, sharing, and talking about your app.
2. Help you to make a better and robust promotional app strategy

13. App event tracking: App Event tracking monitors how your users interact with the important features in your app. If you want to track app events, then you need to configure the SDK or use S2S conversion tracking. Examples of events could include sharing content with a friend, making a purchase, or reaching a certain point in a game.

Why is event tracking important?

1. Helps you to understand your audience
2. To track your conversion goals
3. Helps you to launch advanced targeting programmes

These are the prime key performance indicators (KPIs) or mobile app metrics in 2018 which will help you to know how your app is performing or in which areas you need to keep more focus to win the competition.

Best mobile apps security tips

As the popularity of mobile applications is thriving hurriedly, the companies need to show their concern over the security of applications. An IBM Security study that involved more than 400 large organizations has revealed that nearly 50% of the organizations have zero budget towards mobile security. This is quite shocking because a security breach will not only help you in losing a chunk of money but it also can tarnish the image of your company in the market. So, mobile app security is not a feature or benefits in these days rather it has become necessary for every organization.

There are many app security breaches which an organization should keep in the mind so that they can make their mobile app secure. Below, we are mentioning some best practices that every organization should implement in their mobile app security.

Mobile app security best practices

Write a secure and complex code: If you can write an intricate and complex code for your mobile application, then it will stay safe because the more you write complex codes it will get lesser attacks of the hackers. It would be an arduous job for frauds to understand how your application operates and thus, it will take more time to break your code. You can use code hardening and code signing to make your code more robust and strong. Bugs and vulnerabilities in a code are the starting point from where the attackers can break your code or can tamper with it. So, write an error-free or bug-free application to secure your mobile app from the unscrupulous persons.

Encrypt all your data: Every single data of your app should be encrypted. Encryption is a process which scrambles plain text with no meaning to anyone except those who have the key can understand it. If your data has stolen, then it can not be read or misused by the criminals due to encryption. The power of encryption is so high that eminent organizations like the FBI, NASA even ask permission to access iPhone or decode various Whatsapp messages.

Use secured APIs: Unauthorised APIs are coded loosely and a sagacious hacker can misuse them. That’s why the experts recommend that APIs that are authorized centrally have maximum security. Moreover, a chunk of data gets transmitted between application, servers, and users, if you are using the API. So, APIs should be verified before if you use. Hence, it would be a prudent decision for you if you use secured and authorized APIs.

Use high-level authentication methods: Most of the security breaches happen due to feeble authentication. Hence, it is important to use stronger authentication for your application. Basically, authentication refers to passwords and other personal identifiers that act as fences to entry. Though authentication depends on the users of the application, still as a developer, you must encourage your users to pay an extra attention to authentication. You can design your apps in such a way that it can only accept alphanumeric passwords. You may use multi-level authentication like a combination of password and a dynamic OPT to enhance the security of your app.

Avoid app data caching: mobile apps often capture data in many ways, but developers ignore the vulnerabilities of typical data storage methods. You should prevent data from being stored whenever is possible. You should also prevent HTTP caching in your mobile application. This will help you avoid caching of any data (e.g. registration) and your application will become less susceptible to any cyber- attack.

Deploy anti-tamper techniques: Attackers often tamper various mobile application, then resign them and publish their own version of the original app on third-party marketplaces. Nowadays, the markets are crammed with many techniques which will give you an alert when someone tries to tamper with your code or inject a malicious code. You can employ tamper detection tool to make sure that your code will not work properly if it has been modified.

Pay an extra attention when you are using third-party libraries: You must carefully use third-party libraries and before using them, test the code thoroughly. Though third-party libraries are useful, at the same time they are more vulnerable to an attack and can make your app more insecure. Third-party libraries can contain security holes and various vulnerabilities. For example, The GNU C Library had a security issue and it allowed attackers to remotely execute malevolent code and crashed the system. So, library testing is mandatory before you use them for your app.

Use the principle of least privilege: The principle of least privilege refers that a code should run with the permissions that it absolutely required and no more. Your app doesn’t request for any more privileges than the minimum permission that it needs to run. If you don’t need access to the user’s contacts, then simply don’t ask for it. Don’t make unnecessary network connections because this will lessen your app’s security.

Test rigorously: Securing your app is a time-consuming process and you need to do various tests to ensure that your app is secured. You need to do various testing processes like penetration testing, regression testing, automated testing, exploratory testing, etc. New threats emerge and thus, you need new solutions to conquer them. Hence, by testing, you must fix every issue before marketing your app.

These are the mobile security checklist that every app developer must follow to enhance the security of their apps.


Mobile app security issues

Here, we are mentioning some of the top security issues in the mobile app.

Insecure data storage: As a developer, your core focus is to design apps in such a way that all the imperative and relevant information like password, credit card numbers, etc. don’t reside directly on the device. Data always be stored in the device in an encrypted way. In January 2014, Starbucks mobile app was one of the most used application in the USA and it had 10 million customers. But when CNBC reported that all the credential information of the users found to be stored in plain text format, near about 3 million users deleted the app from their devices. Within 24 hr, the app fell from 4th to 26th rank. Though the company has fixed the issue in the next week, that was too late.

SSL issues: SSL issue is one of the most common issues in mobile apps. Most of the time, SSL certificates are not verified and thus, TrustManager broken. Improper protection of transport layer actually invites the attackers to misuse and exploit your app.

Data leakages: Now, companies are collecting all the personal info of the users so that they can prepare customized marketing strategy to grab the attention of the customers. But it doesn’t compromise a consumer’s privacy. Recently, NSA has reported that a popular smartphone app like Angry Birds gathers the relevant information of a person like age, location, gender, and many more things. This is called a leaky app.

Untrusted inputs: mobile apps accept data from multifarious sources and insufficient encryption gives attackers an easy access to cookies and environment variables. An app which accepts data from external sources should check all the inputs before using them. In 2012, a flaw in Skype security allowed attackers to open the app and dial any random number by using a simple link in the contents of an email.

App security for Android

Your Android phone is crammed with many sensitive and important information. So, it’s a good idea to install some security software on it. Below, we are mentioning some top security apps for Android.

Trend Micro: Trend micro is one of the popular choices for mobile security. It managed 100 percent for real-time detection and 100 percent for malware discovered in the last four weeks.

Avast mobile security: This is a free app for the Android platform. It has a wide range of tools like antivirus protection, web shield, call blocker, app locker, Wi-Fi scanning and many more things. It managed 99.8 percent real-time detection and 100 percent for malware discovered in the last four weeks.

Sophos mobile security: This has many features and is really a good choice for Android. It scores 100 percent detection rate for malware in real-time and cost is zero.

AVL: If you don’t need anti-theft tools or identity protection, all you need is only malware protection, then AVL is the best option for you.

Cheetah mobile security master: This is the newest entrant on the mobile app security but it offers many features. The antivirus protection of this app scans malware and spyware but there is also VPN protection which safeguards your browsing, messaging, online shopping, banking, and many more activities.

Over the past few years, the astounding growth of cyber-attacks had become an agony for every organization. It not only attenuates a company’s growth and productivity but also tarnishes its brand image and reputation. Therefore, this is a high time that every company should adopt a concrete security solution to protect their assets and databases. Mobile app security will definitely become a bigger differentiator in the success and popularity of an app rather than its aesthetic look and usability.

The growth of mobile app development is evolving very rapidly and thus, you can find that these days app stores are crammed with a chunk of apps. So, if you want that your app will get the desired success, you need to follow some strong and robust app marketing strategies and techniques. ASO or App store optimization is a popular app marketing technique which will boost your app’s rank in the app stores.

What is ASO?

ASO is the process of optimizing your mobile apps so that they can get higher ranks in an app store’s search results. The higher your app ranks in an app store’s search results, it will become more visible to the customers. The enhanced visibility will automatically drive more traffic to your app’s page. So, ASO has become an imperative part of a company’s growth and success. Thus, companies are adopting various app store optimization techniques so that they can enhance their customer base.

Why is ASO important?

According to Forrester, 63% apps are discovered through app store searches. If you are not using ASO for your apps, then it would become very difficult for people to notice your app because there are more than 2 million apps in the app stores which are vying with each other in order to get the attention of the customers. So, ASO is your weapon which will not only enhance your app’s rank but also will increase your app’s mileage and visibility. Nowadays, the markets are thronged with many app store optimization services which offer a complete app store optimization techniques to the clients like you.

How to do app store optimization?

Here, we are mentioning some app store optimization tips that you should follow if you want to enhance your app’s rank in the app store’s search results.

1. Know your customers and your competitors: If you want to make a concrete ASO strategy, then you must know your customers and your contenders. You should find how your customers are using your app, what language they are using, what keywords they are typing, what are the reasons for using or downloading your apps, etc. You also need to understand your competitor’s app like what is the uniqueness of their apps, what keywords they are using, why customers are showing their interest in these apps, and many more things. Once you have all the answers with you, then you can only make a robust and stern ASO strategy.

2. Choose low competition keywords: The keywords are the game changer in your ASO. There are millions of apps in the app store. If you want to enhance your app’s visibility and want to get more downloads, then you need to prudently choose your keywords. And for this, you should go for low competition keywords. It is true that popular word must have more traffic than other words, but you will get the repay from these words difficulty. So it would be a wise decision for you if you choose some low competition words to achieve your target. You can use more long tail words to enhance your traffic. Try to use some keywords research tools to find out which keywords have lower competition and search volume so that you can use them for your ASO.

3. Choose a right title for your app: An unique title or name will not only improve your branding but also helps you to get more attention when you are going for ASO. While choosing the title of your app, don’t forget to incorporate your keywords into the title. A plethora of studies has claimed that apps with a relevant keyword in their title ranked, on average, 10.3% higher than apps without a title keyword. Titles in the App Store can be up to 255 characters which means you can incorporate plenty of keywords in the title. But don’t try to incorporate every keyword into your title. Make your title crisp and intriguing because your title is the first and foremost impression on your customers.

4. Make a compelling description of your app: Your app’s description plays an important role in your ASO. This is the part where your users can know about the functions and features of the app. Thus, you need to create some lucrative and compelling content to drive customers to install your app. While writing the description of your app, try to follow the below-mentioned things.

– First three lines of the description should be more intriguing and compelling

– Add keywords in the description

– Mention the features, benefits, and uses of your app

– Give your app link in the description

– Mention the updates

5. Give a unique app icon: There is an endless list of apps in the store, so your visual icon is the first impression which you can’t ignore. When you are planning to design your icon, both App store and Google play have different approaches. For iOS, the icon size should be at least 1024×1024 pixels. From here, the Apple OS will resize your icon for any other applications, including app icons (180×180), navigation icons (66×66), and tab bar icons (75×75).

6. Include some beautiful screenshots: Like an app icon, screenshots can create a great impact on the inherent feelings of your audiences. It is also true that the screenshots can show the function and feature of your app indirectly. When you are planning to optimize your app, take consideration of the screenshots. You can upload up to five screenshots for an iOS app, but only first two or three screenshots will show in the gallery on the page. So, try to upload first two images with high-resolution screenshots because they can convince your customer to browse the other screenshots or download them.

7. Use video to get more customers: Several studies have claimed that 55% customers more easily be influenced by the video advertising. So, video plays a pivotal role in your app store optimization. You can create an effective and attractive video to describe the features and functions of your app. Then, put this video on several social media channels to get more users who will install your app.

8. Use good ratings and reviews: This is another effective app store optimization technique which will drive more traffic to your app page. You can go for the third-party publicity or you may use your own user base of some paid reviews in order to get high-quality ratings which will boost your app’s rank.

9. Update your app frequently: Customers prefer those mobile apps which are improving frequently with regular updates based on the feedback of the customers. Apps that are updated on a regular interval basis get a higher value and more customer-centric. So, try to upgrade your app based on the reviews and feedback. An improved version of the app will certainly get higher ratings than the older versions.
