React Native vs Flutter

React Native and Flutter are both mature, both power apps with millions of users, and both will build your app well if the team using them knows what it is doing. Most comparison pages pick a winner. The more useful question is which one fits the rest of your company: your web stack, your hiring, and the kind of interface you want.

We use React Native, so weigh our view accordingly. We chose it because almost every client we work with also has a web app in React or Next.js, and one TypeScript team across web and mobile is worth more to them than any difference between the frameworks. If that is not true for you, Flutter deserves a serious look.

React Native renders real platform views. A button in a React Native app is an iOS button on an iPhone and an Android button on a Pixel, arranged by your JavaScript code. Since the New Architecture became the default, JavaScript talks to native code directly through JSI rather than through a serialised bridge, which removed the main performance complaint of older versions.

Flutter does not use platform views for its interface. It ships its own rendering engine and draws every pixel itself, using widgets written in Dart that imitate Material and Cupertino styles or follow your own design. That gives you identical rendering on every device and fine control over animation, at the cost of not getting platform controls for free.

Neither approach is better in general. If your brand wants a custom, consistent interface everywhere, Flutter's model is a natural fit. If you want the app to feel like the platform it runs on, React Native's model gives you that by default.

Pick React Native when you have, or will have, a React or Next.js web app. Types, API clients, validation schemas, and business logic can be shared, and the same developers can work on both. For a small company that is often the difference between one team and two.

Pick it when you want over-the-air updates for JavaScript fixes. With Expo, a bug fix that does not touch native code can reach users without a full store release, within the app store rules.

And pick it when hiring matters. TypeScript and React are among the most widely known skills in software, and a good React developer becomes productive in React Native quickly.

Pick Flutter when the app is the product and there is no React web app to share with. A mobile-first company with a small marketing site gains little from React Native's web overlap.

Pick it when the interface is highly custom: heavy animation, a strong brand look that must match exactly on iOS and Android, or a design system that does not want platform controls at all. Flutter's rendering model is built for that.

And pick it when your team already knows Dart and Flutter. A team's existing skill beats any framework advantage, and Flutter's integrated toolchain and widget catalogue are well liked by the people who use them.

For normal app work, such as lists, forms, navigation, maps, and media, both are fast enough that users will not tell the difference. Slow apps in either framework are usually slow because of how they were built: too many re-renders, huge images, or work on the main thread.

Where you need native performance for one feature, such as on-device processing or a custom camera pipeline, both let you write that part in Swift or Kotlin. If most of the app is that kind of work, the better comparison is native against cross-platform, not React Native against Flutter.
