React Native or Flutter: choose based on your team
If your team already writes React and TypeScript, choose React Native. For a separate mobile team or an app that must look identical everywhere, choose Flutter.
If your team already writes React and TypeScript, choose React Native. If you are building a separate mobile team, or your app must look exactly the same on every device, Flutter is a good choice. Both are mature enough for production apps, and we work with both ourselves (see our technology page). In most companies the deciding factor is the team that will build and maintain the app.
The technical difference
React Native uses JavaScript or TypeScript with React. At runtime it creates real Android and iOS views for your components, so the app uses the platform's own buttons, lists and text fields. Since version 0.76 the New Architecture is enabled by default. The documentation recommends starting new projects with a framework and points to Expo.
Flutter uses Dart and draws its own widgets, independent of the operating system's UI library. For release builds Flutter compiles your app to machine code.
| React Native | Flutter | |
|---|---|---|
| Language | TypeScript or JavaScript | Dart |
| Interface | The platform's native components | Its own widgets, drawn by Flutter |
| Sharing code with a React web app | Types, validation, API clients, sometimes logic | Little, different language |
| Look and feel | Follows iOS and Android | Identical everywhere unless you adapt it per platform |
| Hiring | Overlaps with web developers | Mostly mobile developers |
When React Native is the logical choice
If you have a web product in React or Next.js, your developers work on the app with the same language and the same mental model. You share types, validation schemas and API clients between web and mobile, in a monorepo or as a shared package. There is more on that in TypeScript across frontend and backend.
Expo takes a lot of setup off your hands. Among other things you get file-based routing and a standard set of native modules. For most apps that is enough to start with, and you can still add your own native code when you need it.
Hiring matters too. In the 2025 Stack Overflow Developer Survey, 43.6 percent of respondents used TypeScript and 5.9 percent used Dart. You will find people for React Native faster, and a good React web developer can learn the mobile side.
When Flutter fits better
Flutter is a good fit when you have no React team yet and are building a team for mobile only. Dart is a typed language with classes and a familiar syntax, so developers with a background in Java, Kotlin or C# settle in quickly.
Flutter is also strong when design leads. Think of a brand with its own visual identity, lots of animation, and screens that must match pixel for pixel on iOS and Android. Because Flutter draws everything itself, the app looks the same on every version of the operating system. That saves some of the testing on older devices.
What your team has to learn
A web developer who starts with React Native also has to learn the mobile side: Xcode, Gradle, signing builds, app store reviews and testing on real devices. Make sure at least one person on the team knows this well, or every release gets stuck at the last step.
With Flutter the whole team learns Dart. That is manageable, but plan onboarding time for everyone who has not used it before.
Either way you will sometimes need native knowledge, for example for a payment terminal, Bluetooth, background tasks or a third-party SDK without a ready-made binding. With us, you choose who joins your team, so you can select for that. Our way of working explains how.
Test it before you choose
Build the same difficult part of your app in both stacks, not a one-screen demo. I would test this:
- Login with your own identity provider, including token refresh.
- A long list of images that loads from an offline cache.
- A push notification that opens the app on the right screen.
- The one native integration you really need.
- A build to TestFlight and to Google Play internal testing.
Then look at how long it took, how much native code you had to write and which stack the team preferred.
Maintenance after launch
App stores set requirements for the SDK version your app targets. On Google Play, for example, new apps and updates must target Android 16 (API level 36) since 31 August 2026. Plan time every year for framework and SDK upgrades, even when no new features are coming.
With React Native and Expo you upgrade per Expo SDK version, which bundles a React Native version with matching modules. With Flutter you follow Flutter's own releases. Schedule those upgrades as regular sprint work, just like for your web app.

Frequently asked questions
Is React Native or Flutter better for a new app?
Neither is better in general. If your team already writes React and TypeScript, React Native is the logical choice. If you are building a dedicated mobile team or the design must be identical on every device, Flutter fits better.
Can a React web developer build React Native apps?
Yes, the language and the way of thinking are the same. That developer does need to learn the mobile side: native builds, app signing, app store reviews and testing on real devices.
Does a Flutter app look like a regular iOS or Android app?
Flutter draws its own widgets instead of using the ones from the operating system. That makes the app look the same everywhere. If you want it to feel native on each platform, you have to design for that yourself.
