Mobile applications have become part and parcel of everyday lives. From communication (Whatsapp, Facebook), to food deliveries (Zomato, Swiggy) to commute (Uber) & e-commerce (Amazon). The everyday life of people in rural and urban areas has been transformed by the use of these commonplace software.

Mobile app development is a multi-layered process and software companies have been trying to uncomplicate this process with easy to use ADF or application development framework.

What is an app development framework?

It is an assistive platform for creating applications. ADF’s exist to make the task of creating applications faster, easier, and uncomplicated. We are going to cover the top mobile app development frameworks to consider before developing an app.

Mobile application development frameworks deploy visual declarative ways to bypass writing time-intensive codes from scratch.

This means mobile app developers can use drag and drop for commonly used base codes to avoid creating apps from the beginning. Frameworks streamline app production and can consist of the following elements-

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

Companies usually outsource mobile app development because of their existing technology stack and use of the most appropriate development framework.

More than 5 billion people use mobile phones across the world. This number highlights the business importance of creating applications.

Following are the best framework for mobile apps used globally-

React Native

React Native-Top App Development Framework

This is one of the best framework for app development that was conceptualized and created by Facebook’s hackathon project in 2013. It was preceded by Mark Zuckerberg’s public disappointment in choosing HTML over native.

React Native is an open-source framework and by far the most used mobile app framework. 42% of software developers are using it to create cross-platform apps as per a 2020 developer survey conducted by Statista.

Core Features & reasons for the success of react native framework-

  1. Compatible with external plugins : React Native is a cross-platform development technology tool that includes ‘React’, a very well functional JavaScript library that enables easy integration of external plugins.
  2. Cross-platform functionality : React Native truly believes in, ‘learn once, write anywhere’. Thus, its functionalities enable easy code writing for both android as well as iOS platforms.
  3. Cost-effective: React Native enables easy code reuse for both androids and iOS platforms. It also enables sharing of the same code for these platforms, with the common technology of ‘React’. As a result, app developers are able to save on code development time and technology toolkits, resulting in upto 40% of overall cost savings.
  4. A very large community of mobile app developers : Currently, featuring a developer base of more than 1.6 million app developers worldwide, the platform is only set to further expand and grow. Thus, easy technology support is available as and when required.
  5. Modular Architecture: React Native enables modular architecture for code developments as it allows developers to combine all code, files, components, constants, reducers related to a single module into a completely independent module.
  6. Produces very stable applications: Since the JavaScript (language supporting React Native) is the world’s most used programming language with a huge base of already existing and easy to use libraries and APIs that have been often tested across the blocks, the resultant applications are very stable.

Types of app development frameworks

The best mobile app development framework is one that fits your requirements. Out of the existing mobile development frameworks, you will find that there are one or two that seem just right, falling into place like a newly found puzzle piece.

This depends on what platform, budget, and vision you hold for your app. The following are the types of frameworks segregated on the basis of platform and usage.

Cross platform app development frameworks

In a highly competitive application environment, companies don’t want to miss out on any customer demographic especially when they can easily reach both iOS & Android audiences.

Cross-app frameworks allow app developers to create apps that are compatible with both OS- Android & iOS. The code is written only once and the application is set up for both operating systems.

This is a faster & more economic way to create 2 applications with half the effort.

Benefits of creating cross-platform apps-

a) Reusable code

The original code of the application is applicable for both operating systems. This code-reusability also helps in application updation.

b) Low Cost

The cost of creating a cross-platform app is relatively lower than creating a native app.

c) No technical limitation

It is a developer-friendly way to create an app as there is no need to learn a specific native language

d) Faster to make

Cross-platform coding helps in making 2 applications in half the time. This is the faster method of creating apps for both iOS & Android.

The following are some popular frameworks for cross-platform
