React Native vs Flutter: which should you choose for your app?

React Native or Flutter: which one should you pick?

Pick React Native if your team already works in React and TypeScript or you want to share code with a React web app. Pick Flutter if your app needs a highly custom, pixel-identical interface on every device and your team is comfortable learning Dart. Both build real iOS and Android apps from one codebase, both are open source and actively maintained, and both are used in production by large companies. For most business apps, the framework matters less than a tight scope, a solid back end and a clear release process.

Below is how we help clients decide when they ask us to build a mobile app.

How do React Native and Flutter work?

React Native, created at Meta, lets you write the app in JavaScript or TypeScript with React. Your components map to real native views on iOS and Android, so buttons, lists and text inputs behave like the platform's own. The React Native documentation recommends starting new projects with a framework such as Expo, which handles builds, updates and many native features for you.

Flutter, created at Google, uses the Dart language and draws its own interface with its own rendering engine instead of using the platform's native widgets. That gives you precise control over every pixel and very consistent results across devices. The Flutter documentation covers its widget system, state management options and platform integration in detail.

Side-by-side comparison

Which fits your team?

This is usually the deciding factor. An app is not finished at launch: it needs updates for new iOS and Android versions, store policy changes, bug fixes and new features. The framework your team, or your agency, can maintain comfortably for years is the right one.

• If your product already has a React or Next.js web app, React Native lets the same developers work across both, and you can share TypeScript types, API clients and validation rules.
• If you are starting fresh with no existing front-end code, either is fine. Look at who will own the app after launch and what they already know.
• If you plan to hire, check the talent pool in your market for each skill set. React and TypeScript developers are common; strong Dart and Flutter developers are less common in some regions.

Which is better for your design?

If your designers want every screen to look exactly the same on iPhone and Android, with custom animations and unusual layouts, Flutter's own rendering makes that straightforward. If you prefer the app to feel at home on each platform, with native scrolling, text input and navigation patterns, React Native's native components get you there with less effort.

Either way, design the core flows in Figma before writing code. A clickable prototype answers most design questions cheaply, and our UI/UX design work always starts there.

What about performance?

Both frameworks can produce smooth apps. React Native's newer architecture removes much of the old overhead between JavaScript and native code, and Flutter compiles Dart to native machine code for release builds. In real projects, slow apps usually come from the same causes regardless of framework: oversized images, long lists that are not virtualized, too much work on the main thread and slow API responses. Budget time for profiling on real, mid-range devices, not only on the latest flagship phone.

Can both use native features?

Yes. Camera, location, push notifications, payments, biometrics, Bluetooth and background tasks are all available in both ecosystems, through official plugins or well-maintained community packages. When a package does not exist, both let you write a native module in Swift or Kotlin and call it from your app. Before you commit, list every device feature your app needs and check that a maintained package exists for each one in the framework you are considering.

What if you are building an MVP?

For a first version, speed of learning matters more than framework purity. Choose the framework your builders know best, keep the scope to one core user journey and ship to TestFlight and Google Play internal testing early. Many products also start with a responsive web app and add native apps once they have users who ask for them. Our guide to planning an MVP covers how to cut scope, and our SaaS and MVP development service runs from prototype to launch.

What costs more than the framework choice?

• The back end. Accounts, payments, admin panels, notifications and integrations often take as much effort as the app itself.
• Store releases. App Store and Google Play review, screenshots, privacy forms and release management need planning. Our App Store and Google Play release checklist walks through each step.
• Maintenance. Yearly OS updates, dependency upgrades and new device sizes are ongoing work.
• Analytics and crash reporting. You need to see what users do and what breaks, from day one.

A simple way to decide

1. Write down who will maintain the app for the next two to three years and which languages they know.
2. List the device features you need and check package support in both ecosystems.
3. Decide whether you want a native platform feel or one identical design everywhere.
4. Check whether you will share code with a web app.
5. Build a small spike, one real screen with your real API, in the framework you lean towards before committing.

If two or more answers point the same way, that is your framework. If it is still a tie, choose the one your team knows best, because that is the choice you will live with longest.
