The Problem
A consumer startup had separate iOS and Android codebases that were diverging in features and reliability. User complaints about sync issues were increasing.
Our Approach
We unified both platforms on React Native with a custom offline-first sync engine. The new architecture handles conflicts gracefully and works seamlessly offline.

The Challenge
Maintaining two separate native codebases was unsustainable. Features shipped months apart between platforms, and sync bugs were eroding user trust.
Our Approach
We chose React Native for code sharing while maintaining native performance:
- Unified Codebase - 95% shared code between platforms
- Offline Engine - SQLite-backed local state with conflict resolution
- Real-time Sync - WebSocket connection with automatic reconnection
- Native Bridges - Platform-specific optimizations where needed
Results
The app now ships features to both platforms simultaneously. The offline-first architecture eliminated sync complaints and enabled new use cases for users with intermittent connectivity.
