If you want one app for both Android and iOS, the choice usually comes down to Flutter or React Native. Both are mature, well-supported and used by large companies. The right one depends on your app, your team and your plans. Here is a practical comparison.
The two frameworks in one paragraph each
Flutter, created by Google, uses the Dart language and draws every pixel of the interface with its own rendering engine. Your app looks the same on every device, animations are smooth, and the same codebase can also target the web and desktop.
React Native, created by Meta, uses JavaScript or TypeScript and renders real native components. Its modern architecture improves performance and interoperability with native code, and the Expo toolchain makes building, updating and publishing apps much simpler. If your team already knows React for the web, they can be productive quickly.
Comparison at a glance
| Flutter | React Native | |
|---|---|---|
| Language | Dart | JavaScript / TypeScript |
| UI approach | Own rendering engine; pixel-identical on all devices | Native platform components; looks "native" on each OS |
| Performance | Excellent, especially for custom UI and animation | Very good for most business apps |
| Developer availability | Growing quickly | Very large pool, thanks to React on the web |
| Code sharing with a website | Possible with Flutter Web | Business logic and some components shared with a React website |
| Native features | Plugins for most needs; platform channels for custom code | Large library ecosystem; native modules for custom code |
| Over-the-air updates | Requires store releases for code changes | JavaScript updates can be pushed without a store release, within store rules |
Choose Flutter when…
- Your app has a highly custom, branded interface or rich animations that must look identical everywhere.
- You want consistent behaviour across many Android devices, including older and low-cost phones.
- You may also want desktop or kiosk versions from the same code.
- You are starting a team from scratch and are happy to adopt Dart, which most developers pick up quickly.
Choose React Native when…
- Your team or partner already works with React and TypeScript.
- You want to share code with a React website or admin panel.
- You value a native look and feel that follows each platform's conventions automatically.
- Fast over-the-air fixes for JavaScript changes would help your release process.
What about .NET MAUI?
If your business systems are built on Microsoft .NET and your developers write C#, .NET MAUI is worth considering. It lets you share code and skills with your existing .NET applications. It is a good fit for internal business apps, field-service tools and companion apps for desktop software.
What matters more than the framework
For most business apps, both frameworks will do the job well. The bigger factors in success are:
- A clear scope and a good UX, tested with real users before development.
- A well-designed backend and API that can grow with the app.
- Automated testing and a release process that make updates routine rather than risky.
- A team that will maintain the app as Android and iOS evolve.
Budget is part of the decision too. Our guide to mobile app development costs in India explains what drives the price.
Our recommendation
We default to Flutter for consumer apps with custom design, React Native when a client has a React web team or wants to share code with a website, and .NET MAUI for companies invested in .NET. We'll happily recommend the right fit after a short call about your app. Learn more about our mobile app development services or tell us about your app.
