AppX — describe an app, hold the real thing in 30 seconds.
AppX is an AI mobile app builder. Tell it what you want in plain English and it generates a real Expo + React Native app — not a prototype, not a mockup. Scan a QR code with Expo Go and the working app opens on your phone in under 30 seconds. Refine it by chatting, then ship it to the App Store and Google Play.
It is your code, in a standard Expo/React Native repo you can push to GitHub anytime.
If AppX disappeared tomorrow, you could git clone and keep going.

Real code. Real screens. Real preview on real phones.
Six things that set AppX apart from drag-and-drop and prototype tools.
- Multi-screen generation. Describe a whole app and get a complete Expo project — navigation, state, and data flow — not just one screen.
- Live device preview. Scan a QR, Expo Go opens, and you get real device behaviour with sub-30-second rebuilds via a persistent Metro bundler.
- Chat-driven iteration. Edit any screen conversationally with reviewable SEARCH/REPLACE diffs — like pair-programming with a senior engineer.
- App Store submission. Our team handles the build, signing, screenshots, and submission to the App Store and Google Play.
- Real code you own. A standard Expo/React Native repo. Push to your own GitHub whenever you want.
- Frontier models, honest about cost. Gemini 3.1 Pro for plans and Flash for edits; a typical three-screen generation costs only 8–15 credits.
How it works
- Describe — write your idea in plain English, as much or as little detail as you want.
- Generate — AI plans your screens, writes navigation logic, and generates real React Native code, live.
- Preview — scan a QR code with Expo Go and your app is on your phone in under 30 seconds.
- Refine — say “change the color to navy” and every change is applied instantly and pushed to your phone.
- Ship — one build to submit to the App Store and Google Play. You’re live.
