React Native + Expo: one codebase, iOS and Android.
Expo is the standard framework for React Native development. It handles native builds, over-the-air updates, push notifications, and app store submissions — while keeping the development workflow in TypeScript.
Need an Expo developer for a React Native mobile app — new build, feature addition, or fixing issues on iOS and Android
React Native with Expo requires understanding both the JavaScript layer and the native build system. Common challenges:
Native modules: Some features require native code (Objective-C/Swift, Kotlin). Expo's Continuous Native Generation (CNG) and config plugins allow native customization without ejecting.
EAS Build: Expo's cloud build service handles iOS and Android builds without requiring a local Mac for iOS builds. Configuring EAS credentials, build profiles, and app store submission.
OTA updates: Expo Updates enables over-the-air JavaScript bundle updates without app store review. Configuration matters — incorrect update channels push the wrong bundle to the wrong app version.
Expo Router: File-based routing for React Native (like Next.js App Router). Navigation, deep linking, and URL handling require proper configuration.
Performance: React Native apps need native-feeling interactions. Reanimated for animations, FlashList for long lists, and avoiding the JS-to-native bridge in hot paths.

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
Mobile app scope is the feature list and platform targets. Fixed-price for the full platform.
Questions, answered.
Yes, with EAS Build and config plugins. The only exception: apps requiring deeply embedded native SDKs that don't have Expo config plugin support (rare). For standard consumer or B2B apps: Expo handles everything.
Apple: 1-3 business days for initial review. Google Play: same-day to 3 days. Factor this into launch planning.
