Questions before choosing React Native

Is React Native performant enough for production apps?

Yes. RN achieves 90-95% of native app performance with proper architecture. Key is avoiding unnecessary re-renders, image optimization and using native modules for critical operations.

How long does migration from native app to React Native take?

Depends on complexity. Simple app: 3-6 months. Complex with many integrations: 6-12 months. We recommend incremental approach - module by module migration.

Can we use existing native libraries in React Native?

Yes, through bridge. Most popular libraries already have ready wrappers (e.g. Stripe, Firebase). For custom solutions we create our own bridges.

Bring us the product problem. We will map the mobile path.
