React Native vs Flutter in 2025 — which is right for your mobile app?

Web & App Development • technical guide

Language and ecosystem differences

- **React Native**: Uses JavaScript/TypeScript. Reuses existing web development talent, libraries, and React state management paradigms. - **Flutter**: Uses Dart (developed by Google). Features a custom Skia/Impeller rendering engine that compiles directly to native ARM code.

Performance comparison on real devices

In 2025, performance differences have narrowed significantly: - **React Native (New Architecture - Fabric & TurboModules)**: Replaces the legacy JS bridge with direct C++ JSI bindings, enabling 120 FPS animations and instant native module calls. - **Flutter (Impeller Engine)**: Eliminates shader compilation stutter on iOS/Android, delivering smooth 60-120 FPS UI execution.

PSI Square's recommendation by use case

- **Choose React Native**: If building a cross-platform product alongside a React/Next.js web platform where code sharing, shared state logic, and web developer availability matter. - **Choose Flutter**: For graphic-intensive mobile applications or apps requiring identical pixel rendering across older legacy devices.
