React Native:

Backed by Facebook, React Native is a mobile app development tool to build cross-platform apps on iOS, Android, and UWP platforms with an ability to deliver native-like performance.

React Native Development is used by many tech giants such as Instagram, Facebook, Airbnb, Walmart, Tesla, UberEats, and so on.


A Cross-platform app is an app that can be used on multiple platforms using a single code base.

As ‘cross-platform’ and ‘hybrid’ apps are almost similar accept several structure and technology differences, we are referring here to Ionic as a cross-development app development tool. This is because, using Ionic you can build cross-platform Hybrid apps for web, native iOS, and Android platforms


Again, powered by Google, Flutter is a power player when it comes to delivering first-rate native experiences on Android and iOS platforms. Flutter App Development is growing in popularity and often compared with React Native and other best cross-platform app development tools.

It uses Dart, a programming language developed by Google, and also uses many advanced features of popular programming languages.

What’s The Point Of Comparing These 3 Best Tools For Modern App Development?

We have got your back in case you are finding the best tool to develop a new mobile app or revamp an existing app. This post tries to solve all your questions regarding the best cross-platform app development tools and what to choose and when.

We also want to make one thing clear that what to choose and when always remains subjective and depends on many factors. But this post can help you decide the best framework according to your needs.

Core Differences: React Native vs Ionic vs Flutter

When we talk about differences, we generally consider the below-mentioned factors in mind:

Programming language:

React Native uses React library and JavaScript to deliver a native experience on iOS and Android. While Ionic makes the best use of web technologies like HTML, CSS, and JavaScript and requires a Cordova plugin to wrap the applications in native containers.

Flutter is a bit different here as it uses Dart language which is developed by Google. Dart is a modern, multi-paradigm, and objected-oriented programming language used for building apps for web, mobile, and desktop apps.


React Native and Ionic are having strong community support compared to Flutter. Flutter is relatively new in the battle of mobile app development tools, making it less mature than Ionic and React Native. As Ionic is built on AngularJS, almost 6 years ago, resulting in very strong community support in provisions of the quick solution of errors and constant updates.

However, Flutter has made its space and attracted developers to learn Dart which, in turn, helps developers to build high-performing native apps with the support from the Google community.

All of these frameworks seem to be having a bright future as all three are backed by the strongest tech communities from Google and Facebook.


This is one of the deciding factors to choose the best framework.

Although, performance depends on many factors including developers’ efficiency in writing code but, here we are considering it from the runtime perspective.

React Native lets you build an application that provides native look-and-feel by invoking native APIs and components.

Ionic is different than other frameworks as it uses web technologies like HTML, CSS, and JavaScript to create hybrid cross-platform apps. It needs plugins and third-party packages to wrap your application in native cover.

React Native and Ionic both deliver superior performance but Flutter goes a step ahead because there is no native transition or some bridges to connect with the native environment.

Flutter uses Dart which is still new and requires learning Dart to create an application. It is gradually improving and has many to-dos to accomplish.

If we talk about user interface design or front-end environment of these frameworks, they offer high-quality, native-like experiences which are loved by the developer’s community.

Platforms And Popularity:

Going straightforward, React Native is more popular than the other two as many tech giants are using it in their production environment including Facebook, Instagram, Pinterest, Skype, Tesla, Uber, Walmart, Salesforce, Vogue, and so on.

On the other side, Ionic is very popular among web and mobile app developers due to its easy learning curve. It is used by MarketWatch, Pacifica, Sworkit, Nationwide, and many more.

Flutter has just entered the market but grown in popularity in very little time. It is used by AlibabaHamilton MusicalGreenteaGoogle Ads, and so on.

These frameworks are popular in their respective realms and having future plans of enhancement, too.

Architecture And Execution Of Code:

React Native:

Learn once, write everywhere – this principle saves a lot of time and cost as there is no need to build a separate app for different platforms.

Native UI components and features like Hot Reloading make it one of the best cross-platform app development tools available in the market. One of the architectural advantages of React Native app development is JavaScript. React Native offers native capabilities through React and JavaScript to build better apps, quickly.


One codebase, any platform, gives developers a significant benefit of code reusability. Ionic’s powerful features and strong community support help developers to build highly interactive apps in no time. You can also use Ionic with Angular, React, Vue, or JavaScript.


Flutter comparatively offers high performance as it uses Dart language which is an advanced, compatible, and comprehensive language.

Flutter’s engine connects with platform-specific SDKs which gives developers a modern, reactive, and rich set of features that can be leveraged to create beautiful mobile experiences.
