Technology / React Native
React Native app development company
Native-feel iOS and Android apps on a React stack, delivered at a fixed price and date by senior engineers working AI-first.
(01) What we build
What we build with React Native.
MVP mobile apps
A first release on iOS and Android from one codebase, ready to test with real users.
Companion apps for web products
Mobile apps that share logic, types and APIs with an existing React web product.
Fintech and payment apps
Onboarding, KYC capture, card and wallet flows with biometric login and strict validation.
On-demand and booking apps
Maps, scheduling, payments and push notifications for apps that connect customers and providers.
Offline-first apps
Local storage and background sync for field teams and users with unreliable connections.
Expo-based builds
Fast iteration and over-the-air updates using Expo, with custom native modules when a feature needs them.
(02) Why Techrays
Fixed price, AI-augmented, yours.
Fixed price across iOS and Android
One React Native codebase serves both platforms, so the proposal covers both under one price and date. Anything specific to a platform is called out in the scope instead of appearing later.
AI-assisted, tested on devices
AI drafts screens, tests and API code, and engineers verify behaviour on real iOS and Android devices. Senior review covers navigation, performance and permissions before each release.
Open source, no lock-in
React Native and its libraries are open source. We deliver the app, build configuration and store assets to you, so any React developer can continue the work.
