Building one app for both iOS and Android used to mean accepting compromises. Today the leading cross-platform options are mature, well supported and used in large, demanding apps. The question is less "is cross-platform good enough?" and more "which approach fits this product?"
The main options
- Flutter draws its own interface, which gives pixel-consistent UI across platforms and a single codebase from interface to logic.
- React Native renders native components from JavaScript or TypeScript, and its new architecture — now the default — has removed many of its old performance bottlenecks. It suits teams already fluent in React.
- Kotlin Multiplatform shares business logic across platforms while leaving each interface native, with Compose Multiplatform available for teams that want to share UI too — JetBrains now considers it stable on iOS.
How to choose
- Your team. The framework your engineers already know well usually beats the theoretically better one.
- Your interface. A highly branded, custom UI favours Flutter; an app that should feel exactly like each platform may favour native UI with shared logic.
- Native depth. Heavy use of platform APIs, background work or new OS features argues for keeping native code close at hand.
- Code beyond mobile. Sharing with a web app or backend can tip the balance toward TypeScript or Kotlin.
When native still wins
Apps built around the camera, audio, complex gestures or the very latest platform features often justify fully native development. So can products where one platform dominates the audience.
The stack is only half of it
Whatever you choose, the quality of the app depends on everything around the framework: automated release pipelines, crash reporting, analytics, performance budgets and a plan for OS updates. Those are what keep an app healthy once it is in people's hands.
