Flutter and React Native both build Android and iOS apps from one codebase. Compare performance, UI, team skills and cost to pick the right one for your app.
Cross-platform frameworks let you build one app for both Android and iOS. The two most popular choices are Flutter (by Google) and React Native (by Meta).
Flutter in short
Flutter uses the Dart language and draws its own UI, so the app looks the same on every device. It is known for smooth animations and consistent design.
React Native in short
React Native uses JavaScript/TypeScript and React. It renders native components and lets teams share knowledge — and sometimes code — with a React web app.
How to choose
- Your team – a team that knows React will be productive with React Native quickly.
- Design – highly custom, animated interfaces are often easier in Flutter.
- Web code sharing – React Native fits well if you also have a React website.
- Device features – both support camera, maps, payments and push notifications through plugins.
When native is still better
Choose native Swift (iOS) and Kotlin (Android) for heavy 3D, advanced AR, or apps that depend on the newest platform features on day one.
Conclusion
Both frameworks are production-ready. Pick the one that matches your team and your design goals — the quality of the development work matters more than the framework.
Frequently asked questions
Is a cross-platform app cheaper?
Usually yes, because one codebase serves both platforms. Testing and store releases are still needed for each platform.
Can I switch frameworks later?
It is possible but means rewriting the app. Choose carefully at the start and keep business logic in your back-end APIs.
