Flutter or React Native? How we actually choose

Clients ask us this more than any other question. The honest answer: both frameworks can ship an excellent app, and both are used in production by large companies. The choice rarely comes down to raw performance. It comes down to your team, your design and what the app has to do on the device.

Here is the checklist we use in the first week of a mobile project.

1. Who will maintain it?

An app lives for years after launch, so start with the people who will look after it.

• You already have React developers. React Native lets them contribute from day one. They know JavaScript or TypeScript, the component model and most of the tooling. Shared validation, API clients and business logic can live in one package used by both the web app and the mobile app.
• You are starting fresh. Flutter's single toolkit — one language (Dart), one UI framework, one official set of widgets — makes onboarding predictable. A new developer learns one way of doing things instead of choosing between libraries.

Hiring matters too. In India there are more JavaScript developers overall, but experienced Flutter developers are easy to find for product work. Whichever you choose, pick the option your future team can own without us.

2. How custom is the design?

Flutter draws every pixel itself. It does not use the platform's buttons or lists; it renders its own. So a highly custom design — curved tab bars, glassy cards, bespoke animations, a brand-specific look — comes out identical on Android and iOS, and on old and new phones alike.

When we built the two HireBuddy apps from a detailed Figma file, this was the deciding factor. The design had custom bottom sheets, map overlays and illustrated empty states, and we wanted them pixel-identical across platforms.

React Native uses the platform's own components. That is an advantage when you want the app to feel like a standard iOS or Android app: native navigation, native text inputs, system date pickers and accessibility that behaves exactly as users expect.

A simple rule of thumb:

Your design	Lean towards
Strong custom brand, lots of animation	Flutter
Standard platform look, forms and lists	React Native
Must match an existing React web app closely	React Native

3. What does the app need from the device?

Maps, camera, location, payments, biometrics and push notifications are well covered in both ecosystems. Problems start with less common needs:

• Bluetooth devices, printers or custom hardware;
• long-running background work, such as tracking a delivery route;
• deep integration with one platform, such as widgets, CarPlay or Wear OS.

For these, check the plugin ecosystem before choosing, and be ready to write a small native module in Kotlin or Swift. Both frameworks support this well; it is just extra work to plan for.

4. How will you ship updates?

React Native with Expo can push JavaScript-only fixes to users without a store release, within the rules of the App Store and Play Store. That is valuable for products that change every week. Flutter apps generally go through a normal store release for every change, which is fine with a good CI pipeline but slower for urgent fixes.

5. Performance — usually not the deciding factor

For typical business apps — lists, forms, maps, chat, payments — both frameworks feel smooth when built well. Performance problems almost always come from the code, not the framework: oversized images, rebuilding whole screens on every change, or chatty network calls. We profile on a mid-range Android phone, because that is what most users in India actually carry.

Our default

• New product, custom design, no existing React team: we start with Flutter.
• Company with a React web app that wants shared logic and one hiring pool: we choose React Native with Expo.

Either way, we decide in the first week — with a short spike on the riskiest screen — not after months of debate. If the spike shows a problem, changing course costs a few days, not a few months.
