How to Build Mobile Apps on Replit
Replit lets you build real iOS and Android apps in the cloud with Expo and React Native — no Mac or local setup. Here's the step-by-step: remix, prompt the AI Agent, preview on your phone, and publish to the stores.

Step by step
1. Remix the Expo template
In Replit, open the Expo template and click 'Remix' to copy it into your account — all files, configs, and dependencies are pre-installed, so there's nothing to set up locally.
2. Describe your app to the Replit AI Agent
Use Replit's AI Agent/Assistant to generate features by prompt — 'add a list screen and an add-item form', 'add a tab navigator' — in React Native. It writes and edits the code for you.
3. Preview live on your phone
Click Run; the console shows a QR code. Install the free Expo Go app on your phone and scan it to load your app instantly on the real device — every change hot-reloads.
4. Add backend and data
Wire in a database, auth, and APIs (Replit supports databases and integrations) so your app stores and syncs real data, not just static screens.
5. Build and publish to the stores
When it's ready, use Expo's build service (EAS) to produce iOS and Android binaries and submit them to the App Store and Google Play. Expo handles the native build so you don't need Xcode/Android Studio set up locally.
Frequently asked questions
Can you build mobile apps on Replit?
Yes. Replit is a cloud IDE where you can build real cross-platform mobile apps using Expo and React Native — one JavaScript/TypeScript codebase that ships to both iOS and Android. The fastest path is to remix Replit's Expo template (dependencies pre-installed), build features with the Replit AI Agent by prompting, preview live on your phone via the Expo Go app and a QR code, then use Expo's build service to publish to the app stores. Because it's cloud-based, there's no local setup like Xcode or Android Studio to configure.
How do you build a mobile app on Replit step by step?
(1) Remix the Expo template on Replit so everything's pre-configured. (2) Use the Replit AI Agent to generate screens and features by describing them in plain language. (3) Click Run and scan the QR code with the Expo Go app to preview live on your phone with hot reload. (4) Add a database, authentication, and APIs for real data. (5) Use Expo's EAS build service to produce iOS and Android binaries and submit them to the App Store and Google Play. Teams can have a working app previewing on a phone in under 30 minutes.
Do I need a Mac or Xcode to build an iOS app on Replit?
No — that's a key advantage. Because Replit runs in the cloud and Expo handles native builds through its EAS service, you can develop and even produce an iOS build without owning a Mac or installing Xcode locally. You preview on a real iPhone using the free Expo Go app, and Expo compiles the store-ready binary in the cloud. (You'll still need an Apple Developer account to publish to the App Store.)
Is Replit good for mobile app development?
It's a strong choice for fast, cloud-based cross-platform development, especially for prototypes, MVPs, and learning, because it removes local setup and pairs an AI agent with the proven Expo + React Native stack. For very large, performance-critical, or deeply platform-specific native apps, a traditional local toolchain still gives more control. But for getting a real iOS/Android app from idea to a phone quickly, Replit + Expo is excellent.
Replit vs Lovable for mobile apps — what's the difference?
Replit builds true cross-platform native apps (iOS + Android) via Expo and React Native, which you publish to the app stores. Lovable builds mobile-friendly web apps and PWAs rather than native binaries — great for a responsive web experience, but for App Store/Play Store distribution you'd export and wrap it. Choose Replit (Expo) if you specifically need native store apps; choose Lovable if a fast mobile-web/PWA experience is enough. See our guide on building mobile apps with Lovable for that path.
