Why startups choose React Native

React Native builds iOS and Android apps from one TypeScript codebase while rendering real native components, so the app feels at home on both platforms. For startups that means one team, one codebase, and faster releases than building two separate native apps.

It also shares a language and patterns with React and Next.js on the web, so a mobile app and a web dashboard can be built and maintained by the same developers. Our React Native vs Flutter guide compares the two leading cross-platform options in detail.

Expo, native modules, and over-the-air updates

We build most apps with Expo, which handles builds, app signing, and store submissions and provides a large set of maintained native modules for the camera, notifications, location, payments, and more. When a project needs custom native code, we add it through development builds without leaving the Expo workflow.

Over-the-air updates let you ship JavaScript fixes and small improvements to users without waiting for a full store review, while native changes still go through the normal release process.

Hire React Native developers, without the hiring

Hiring a senior React Native developer takes time, and a single hire still needs design, backend, and release support around them. Working with Codeles gives you a founder-led team that covers product scoping, UI, React Native development, backend, and store releases — and can work alongside your existing developers.

We can take full ownership of an app, extend one your team already built, or help stabilise and modernise an older React Native codebase through our app maintenance service.

React Native app development cost

A React Native MVP typically falls between $8k and $18k for a standard app on both iOS and Android, with simpler apps below and multi-role, real-time, or AI-heavy apps above. Our app development cost guide breaks down what drives the price.

FAQ

Can you take over an existing React Native app?

Yes. We start with a short code audit, fix the most important stability and upgrade issues, and then continue feature work.

Do you publish the app to the App Store and Google Play?

Yes. We prepare builds, store listings, screenshots, and submission details, and handle review feedback until the app is live.

Expo or bare React Native?

We default to Expo when it fits. We recommend ejecting or adding native modules only when a required capability is not available otherwise.

Can you work inside our monorepo?

Yes, when access and conventions are clear. We adapt to your package manager and CI rather than forcing a greenfield layout.

How is this different from your Mobile App Development service?

This page is about React Native and Expo engineering specifically. If you're still deciding whether to build a mobile app at all, our Mobile App Development page covers that product-level decision.
