®Flutter and React Native both let one team ship to Android and iOS, so both can reduce the cost of building the same app twice. The right choice depends less on benchmarks and more on your product and your team.
How they differ
Flutter uses the Dart language and draws its own interface. Your app looks nearly identical on every device, which is useful when you have a strongly branded design.
React Native uses JavaScript or TypeScript and renders with native platform components. If your company already has React web developers, they can become productive quickly and share some logic with your website.
When Flutter is the better fit
- You want a custom, heavily animated interface
- You want the same look on Android and iOS
- You are starting with a new team and have no existing JavaScript code
When React Native is the better fit
- Your team already works in React
- You want to share business logic with a web app
- You want the app to follow each platform's native look closely
When neither is right
Some apps should still be native. If your product depends on heavy graphics, complex background processing or the newest platform features as soon as they ship, Swift and Kotlin may save you trouble later.
A simple way to decide
Write down your three most important screens and any hardware features you need, such as Bluetooth or camera processing. Then ask which team you can hire and keep. A framework your team knows well usually beats a slightly better one it does not.
If you are unsure, build the riskiest feature as a small prototype first. A week of testing is cheap compared with changing frameworks later. Our mobile app team can help you test the idea.
