Build a mobile app with Claude Code + Expo
Hey! 👋 Here's what I promised you:
The complete guide to building your iOS + Android app with Claude Code even if you don't understand code — the same steps I used myself: I built an app from A to Z and it got accepted on the App Store and Play Store. 💪

- Install Expo — it's what sets up the file structure and the system your project will run on:
npx create-expo-app@latest my-app
- Work screen by screen — don't tell Claude Code to do everything in one go (impossible + it triggers hallucination). Give it the screens one by one, explain the features of each screen, and give it examples you want it to build like:
sawb liya l-screen dyal login: email + password + button dyal "Sign in", b7al had l-example: <screenshot>. ma tzid 7ta screen okhra daba.
- Stay on top of the details — make sure every button is connected to the other screens before you move on to the next one.
- Test on the phone — open Expo Go on your phone (or connect the phone directly to the PC), scan the QR code, and see how the app looks. If you want to test it on iPhone → TestFlight.
- Publish — you get an Apple Developer account + Google Play Console and submit the app:
⏱️ If the app is simple (3-4 pages) you can build it in a day. If it's bigger, give it two-three months — that's normal. Mine took me about 4 months, and I understood nothing about code.
