Migrate Native Apps to React Native
Unify your iOS and Android development into a single codebase. Ship features simultaneously on both platforms with one team.
Migration: Native to React Native
From Native iOS/Android to React Native
Why Migrate
- Single Codebase: Maintain one codebase instead of two. Share 80–95% of code between iOS and Android, cutting development and maintenance effort nearly in half.
- Faster Feature Delivery: Build features once and deploy to both platforms. No more waiting for the Android team to catch up with the iOS release or vice versa.
- Unified Team: Hire JavaScript/TypeScript developers instead of maintaining separate Swift and Kotlin teams. Reduce hiring costs and improve team velocity.
Migration Roadmap
- Native App Audit (1–2 weeks): Catalog all screens, native APIs used (camera, GPS, push notifications), and platform-specific features. Design the React Native architecture.
- Screen and feature inventory
- Native API usage mapping
- React Native architecture document
- Screen-by-Screen Migration (6–12 weeks): Rebuild screens in React Native starting with the simplest. Use native modules for platform-specific APIs. Test on both iOS and Android.
- React Native screens with platform parity
- Native module bridges for device APIs
- Cross-platform UI test suite
- App Store Transition (1–2 weeks): Submit the React Native app to both app stores, migrate push notification tokens, and transition users with an in-app update prompt.
- App Store and Play Store submissions
- Push notification token migration
- User transition and analytics validation
Risks & Mitigation
- Performance-critical features run slower in React Native: We implement performance-critical modules (animations, video processing) as native modules in Swift/Kotlin, called from React Native via the bridge.
- Platform-specific UX patterns feel wrong on one platform: We use Platform.select and platform-specific components to deliver native-feeling UI on each platform while sharing business logic.
Estimated Scope
Hours: 200–400 | Cost: $400–$800 | Timeline: 8–16 weeks
Frequently Asked Questions
- Will the React Native app feel native?
- Yes. React Native renders native UI components, not web views. With the New Architecture (Fabric), performance is nearly indistinguishable from fully native apps.
- Can we keep some native modules?
- Absolutely. React Native supports native modules for performance-critical or platform-specific features. Many apps use a hybrid approach.
- What about app store approval?
- React Native apps go through the same review process as native apps. We ensure compliance with both Apple and Google guidelines throughout development.
