Trusted in production by:
Expo is a React Native framework built for React developers. Your components, hooks, and routing patterns work on iOS and Android. No new language, no Xcode, no Android Studio.
You don't need to become a native developer. You just need Expo.

The React you know works. The tools are already there. Here's what you get on day one.
File-based routing, like Next.js.
Expo Router gives you the same intuitive file-based navigation you use on the web. Nested routes, dynamic segments, and layouts. All familiar. Define a route by creating a file.
One codebase. iOS, Android, and web.
Share logic, components, and styles across all three platforms from a single repository. Platform-specific code where you need it, shared everywhere else.
No Mac. No Xcode. No Android Studio.
EAS Build handles native compilation in the cloud. Push your code, get a TestFlight link or Play Store build back. No local native toolchain required. Ever.
React Native uses the same component-based model as React. Most of your app code will be in JavaScript or TypeScript, so the patterns and libraries you already know continue to apply.
React Native renders to actual platform primitives, not webviews. Your components map to real iOS and Android UI elements, giving you the performance and polish users expect.
From a single project you can target iOS, Android, and web. With Expo Router and API Routes, even your navigation and backend logic can be shared across platforms.
TypeScript, all the way down.
Write TypeScript for your mobile app the same way you write it for the web. Full IDE support, type-safe navigation with Expo Router, and typed native APIs out of the box.
Instant feedback while you build.
Fast Refresh updates your running app instantly on save. No full reload, no losing state. The development loop feels as tight as working in a browser.
Your existing npm packages.
Most JavaScript libraries work in Expo out of the box. Zustand, React Query, Axios, date-fns. Your existing dependencies come with you to mobile.
Ship fixes without resubmitting.
EAS Update pushes JavaScript changes directly to users' devices. No new binary, no App Store review wait. Fix a bug and have 95% of active users on the new version within minutes.
See it on a real device in seconds.
Expo Go lets you preview your app on a physical iOS or Android device the moment you start. No provisioning profiles, no simulator setup, no waiting.
Docs written for web developers.
Expo's documentation assumes you know React, not native development. Tutorials, guides, and API references are built around the web developer's path to mobile.
Sign up free and have Expo running in minutes. No credit card required. No native experience needed.
