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

  1. 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
  2. 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
  3. 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.
