React Native is a proven choice for startups. Our team has delivered hundreds of startups projects with React Native, and the results speak for themselves.
Startups rarely have the budget to build two separate native apps. React Native shares 80-95% of code between iOS and Android, meaning one team can build for both platforms simultaneously. The framework is backed by Meta, used by companies like Instagram, Coinbase, Shopify, and Discord. With Expo, you get over-the-air updates (push bug fixes without App Store review), a managed build service, and access to native APIs through a simple JavaScript interface.
Share 80-95% of code between iOS and Android. One developer can build and maintain both apps.
Building two native apps costs 1.8x a single app. React Native brings this down to 1.2-1.3x, saving $20,000-$80,000 on an MVP.
If your team knows React (for your web app), they can build the mobile app too. No need to hire separate iOS/Android specialists.
Push bug fixes and minor updates instantly without going through App Store review. Critical for fast-moving startups.
Building startups with React Native?

Schedule a CallBefore choosing React Native for your startups project, validate that your team has production experience with it — or budget for ramp-up time. The right technology with an inexperienced team costs more than a pragmatic choice with experts.
React Native has become the go-to choice for startups because it balances developer productivity with production performance. The ecosystem maturity means fewer custom solutions and faster time-to-market.
| Layer | Tool |

| Framework | React Native + Expo |
| Navigation | Expo Router |
| State | Zustand / React Query |
| Backend | Supabase / Firebase |
| Push | Expo Notifications |
| CI/CD | EAS Build + EAS Submit |
A startup mobile app on React Native with Expo typically takes 8-14 weeks to build. The developer writes React components using React Native primitives (View, Text, ScrollView) that render to native iOS and Android widgets. Expo provides pre-built modules for camera, location, push notifications, biometrics, and more — no native code required.
The backend is typically Supabase or Firebase, providing auth, database, and real-time features. EAS Build compiles the app in the cloud and EAS Submit pushes it to the App Store and Play Store. Post-launch, EAS Update enables instant bug fixes without a full app review cycle.
