If you want one app on both iPhone and Android without building it twice, the two main choices are Flutter and React Native. Both let one team ship to both platforms from a single codebase. They get there in different ways, and that difference shapes speed, look and feel, and hiring.
This guide compares Flutter and React Native in plain terms and helps you pick the right one for your app.
What Flutter is
Flutter is Google's framework for building apps from one codebase, written in the Dart language. Flutter draws every pixel of the interface itself using its own rendering engine. That gives you consistent visuals on every device and smooth animations, because the app does not depend on each platform's built-in buttons and screens.
What React Native is
React Native is Meta's framework for building mobile apps with JavaScript or TypeScript and React. It renders real native interface components on each platform, so a button on iOS looks like an iOS button. Teams that already build web apps in React can reuse their knowledge and some of their code.
Flutter vs React Native at a glance
| Flutter | React Native | |
|---|---|---|
| Language | Dart | JavaScript or TypeScript |
| Interface | Drawn by Flutter, same on every device | Native platform components |
| Backed by | Meta | |
| Strengths | Custom designs, animations, consistent look | Native feel, shared skills with React web teams |
| Hiring pool | Growing, Dart is specific to Flutter | Large, built on JavaScript and React skills |
| Also targets | Web and desktop from the same code | Web through React Native Web, with more setup |
When to choose Flutter
- Your app has a strong custom design or brand look that should be identical everywhere.
- Animations and smooth transitions are central to the experience.
- You want one team to cover mobile and possibly desktop or web from the same code.
- You are starting fresh and have no existing React codebase to reuse.
When to choose React Native
- Your team already builds web apps in React and TypeScript.
- You want the app to feel like a standard iOS or Android app.
- You plan to share logic, types, or API code with a React or Next.js website.
- Hiring speed matters, since JavaScript developers are easy to find.
What matters more than the framework
For most business apps, both frameworks are capable. The bigger risks sit elsewhere:
- Scope. A clear first version with a few core screens ships faster than a long feature list.
- Native features. Check early how the app will use the camera, payments, location, or notifications. Both frameworks support these, but some need extra native work.
- Backend. The app needs an API, user accounts, and data storage. Plan these at the same time as the app.
- Store releases. Apple and Google review apps before release. Leave time for reviews and fixes.
- Maintenance. Operating systems update every year, so budget for ongoing updates after launch.
FAQ
Is Flutter faster than React Native?
Both perform well for typical business apps. Flutter has an edge for heavy animation and custom drawing. React Native has improved its performance a lot with its newer architecture. Test the screens that matter most to you.
Can I switch later?
Switching means rewriting the interface, so it is expensive. Choose based on your team and design needs at the start.
Do I need separate iOS and Android developers?
Usually not. One cross-platform team can cover both, with occasional native work for specific device features.
