In 2021, we are witnessing sea changes across industries. Enterprises are striving to create digital-first and customer-focused applications to acquire new and retain existing customers. 

Are you one among them? 

Would you like to grab your customer’s attention with a customized mobile app?  

Then, have you ever wondered what makes a mobile app intrigue and drive users to hang on? Undoubtedly, it’s a mobile app development framework, technology tools, and the platforms developers use.

With more than 5 billion active smartphone users, mobile applications have become an integral part of our day-to-day operations, including communication to food delivery, gaming, entertainment, commute, and shopping. Surprisingly, we are spending more than 70% of time on mobile apps to fulfill our needs.   

In the current competitive market, if your business is not yet available on the Play Store, you will be losing new business opportunities coming all the way. Thus, having a customized mobile app with the best development framework is the need of the hour. 

A framework offers a fundamental structure to apps for their execution. There is a huge list of robust, secure, and high-performing mobile app frameworks available in the market. However, you need to be very specific about choosing the best app framework to make your business agile and accessible.

What is a mobile app development framework?

A mobile app development framework is a collection of libraries/tools used to develop platform-specific applications. It provides a fundamental structure that supports mobile app development and boosts the process while cutting down the costs. 

Precisely, by using app development frameworks, developers can save time from writing lengthy codes from scratch. Furthermore, mobile app frameworks allow you to drag and drop a few commonly used base codes to make the process easy and effective. 

However, the mobile app development industry is going through a competitive phase to provide a superlative customer experience across the platforms. 

In fact, modern businesses are more likely to build cross-platform applications to save time and cost. 

Mobile development frameworks consist of the following elements

  • Predefined classes & functions
  • Code libraries
  • Compiler
  • Managing hardware device
  • Interact with system software
  • Assistive programs to help software development

Why do you need mobile app development frameworks?

  1. You can save time from writing lengthy codes.
  2. Code reusability across platforms.
  3. Apps customization according to your business requirements. 
  4. You can build scalable and secure applications.

And before you know about the top 5 mobile app development frameworks, understand the top 3 categories of mobile applications.

Top 3 categories of mobile applications frameworks:

Primarily mobile application frameworks are classified into three categories. 1. Native framework for platform-specific apps, 2. Mobile web app frameworks, and 3. hybrid app frameworks.

1. Native mobile apps:

A native app is an application software specifically designed for a platform or device. If your audiences are specific to a platform, you can develop customized native apps to nurture them. Comparatively, a Native mobile application development cost is relatively higher than other apps. 

Ex: Tweetbot, Overcast, and Bear apps are exclusively designed for the iOS platform.

2. Web applications:

Unlike traditional computer-based software programs, web apps utilize web browsers and web technology to perform tasks over the internet. Web app is a collection of design concepts, technologies, and web APIs to render an app-like user experience on the mobile web. They deliver an intriguing user experience with a few limitations. 

Ex: Twitter, Uber, Telegram, Washington Post

3. Hybrid or cross-platform apps:

A hybrid app is a combination of both native and web applications. They are accessible on multiple platforms with a single code base. In this, you need not invest an exorbitant amount to develop apps for multiple platforms. With little changes to the code, you can have an app that can seamlessly serve your purpose.  

Ex: Facebook, Twitter, Instagram, LinkedIn, and the list goes on and on.

Let’s look at the top custom mobile application development frameworks in 2021 that can help you build cost-effective and scalable applications. 

1. React Native:


React Native is an open-source mobile app development framework launched by social media giant Facebook in 2013. The React Native app framework is based on ReactJS and JavaScript, allowing developers to build cross-platform applications. 

Although it was launched in 2013, React Native has gained momentum due to its scalability and code reusability. You can develop an app for both Android and iOS platforms with a single code base. 

Benefits of React Native app framework:

  1. Code reusability and cost-effective development
  2. Easy to integrate with third-party applications like payment gateways
  3. Ease of maintenance
  4. Support from a large community of mobile app developers
  5. Modular architecture allows you to break down the app code into individual blocks making the structure less complicated
  6. Delivers optimal performance across platforms

2. Flutter:


Compared to React Native, Flutter is the latest mobile app development framework launched by Google in 2018. According to a Google report, more than 2 million app developers have used it since its launch in 2018. 

What makes the Flutter framework so popular? 

If you want to build intuitive mobile apps without compromising quality, the Flutter framework has evolved as the best solution for many app developers. 

Flutter is an open-source UI framework launched by Google to support native mobile apps. It is more like a software development kit comprising all the tools and graphics used in app development. 

The Flutter app framework was written in Dart language. It allows you to customize the widgets of your mobile app, further enhancing the native app experience.

Similar to the React Native framework, Flutter also supports cross-platform application development. 

Benefits of Flutter app framework:

  1. Less development time
  2. Customizable UI designs
  3. Provides Full-native performance
  4. Multiple IDE support

3. Ionic app framework:


It is one of the widely used app development frameworks to build multipurpose and cross-platform applications. The Ionic mobile app development framework is open-source and allows developers to create apps for Android, iOS, and Windows platforms.

Ionic app development framework uses web technologies like HTML, JavaScript, and CSS. Furthermore, the Ionic framework provides mobile-optimized components and native APIs using Cordova and Ionic Native. 

Benefits of Ionic app framework::

  • Faster Application Development
  • Availability of Cordova Plugins
  • Built-in UI components
  • Platform Independent
  • It works well with the power SDK such as Angular and PhoneGap

4. Xamarin mobile app development framework:


Along with the tools and platforms, the cost is also a crucial factor in application development. If you want to develop an app for Android, iOS, and Windows platforms with a single code base, you can prefer the Xamarin framework.

Xamarin is an open-source, cross-platform mobile app development framework acquired by Microsoft. It uses .Net and C# programming languages to build cross-platform mobile applications.  

The Xamarin framework consists of three components: Xamarin Platform, Xamarin Cloud, and Xamarin Insights. 

Xamarin Platform provides APIs, controls, run time engines, encryption, authentication, virtual machines, and every other coding tool. Xamarin Cloud is an automated testing platform that allows developers to test the quality on various devices. And Xamarin Insights tracks application crashes and exceptions in real-time.
