React Native development services cover building iOS and Android apps from a single JavaScript or TypeScript codebase using the React Native framework from Meta. A typical engagement includes architecture, UI implementation, custom native modules for camera, Bluetooth, or biometrics, backend and API integration, automated testing, App Store and Play Store submission, and over-the-air updates after launch. Codazz builds on the New Architecture: Fabric, TurboModules, and Hermes.

Why React Native Dominates Cross-Platform Development

Single Codebase

Write once, run everywhere. A single JavaScript/TypeScript codebase powers both iOS and Android apps, eliminating duplicated logic and keeping your team focused on features.

Near-Native Performance

React Native's New Architecture with TurboModules and Fabric renderer delivers performance indistinguishable from native apps for 95% of use cases.

Hot Reloading

See changes in milliseconds with Fast Refresh. React Native's developer experience dramatically accelerates iteration speed during development.

Massive Ecosystem

Leverage the entire JavaScript/npm ecosystem, React web expertise, and thousands of React Native packages. Your web React developers become mobile developers overnight.
