iOS and Android from one codebase.
Cross-platform development with React Native and Expo means one TypeScript codebase for both iOS and Android. The same developer, the same code, the same deployment process — not two native apps that drift apart over time.
Need both iOS and Android — don't want two separate native codebases to maintain
The alternatives for mobile development:
Native iOS (Swift) + Native Android (Kotlin): Maximum platform integration. Two separate codebases. Two development tracks. Features ship to iOS before Android (or the reverse). Bug fixes applied twice. Twice the cost.
React Native with Expo: One TypeScript codebase. 95-98% code shared between iOS and Android. Platform-specific code for the remaining 2-5% where iOS and Android behave differently.
Flutter: Google's cross-platform framework with Dart. Good performance, different language. Best for: teams already using Dart, or applications with complex custom UI.
Progressive Web App: Web app that's installable from the browser. Not in the App Store. Good for: web-first products where app store presence isn't required.
The React Native decision: React Native is the right choice when: the team knows JavaScript/TypeScript, the application features are standard (auth, API calls, navigation), and the deployment timeline benefits from a single codebase.
Where cross-platform has friction: Platform-specific UX patterns (Material Design on Android, Human Interface Guidelines on iOS). React Native handles this with platform-specific stylesheets. Heavy native features (AR, deep ML integration) may need native bridges.

One honest number to start.
Fixed-scope, fixed-price. The number below is the starting point — final scope is built from your brief.

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
Cross-platform scope is the feature set. Fixed-price for both platforms, not twice the price of one.
Questions, answered.
Yes for most applications. Animations via Reanimated, lists via FlashList, and images via Expo Image give native-quality performance. The gap with native is negligible for standard UI interactions.
