Introduction to AppX
Describe an app. Hold the real thing in 30 seconds.
AppX turns a plain-English description into a real React Native (Expo) app you can run on your phone — no coding, no Xcode, no Android Studio, no build chains to configure.
What is AppX?
You describe what you want to build. AppX's AI plans the screens, generates clean React Native code, and gives you a QR code. Scan it with Expo Go and the app opens on your phone in seconds. Don't like something? Just say so in chat — "make the header dark," "add a settings screen," "the save button overlaps the keyboard" — and watch it update live.
When you're ready, publish to the App Store and Google Play, or share a link.
How it works
- Describe — "Build a habit tracker with streaks, reminders, and a progress chart."
- Generate — AppX plans the screens and writes real React Native code for each one.
- Preview — Scan a QR code with Expo Go and see your app live on your phone. Changes show up in seconds.
- Refine by chat — "Make the button blue." "Add a dark theme." "Show a confirmation before delete."
- Publish — Ship to the App Store and Google Play, or share a web link.
What makes it different
Real code, not a builder export
Every app is a real Expo project — StyleSheet for layout, lucide-react-native for icons, standard React Native libraries. You can read every file, edit it directly, and take the code anywhere. Nothing is locked in a proprietary visual format.
Live preview on a real device
Your app runs on your actual phone through Expo Go, not a faked-up simulator. Tap through it exactly as your users will. Every edit pushes to your phone in seconds — no rebuild, no reinstall.
Chat-driven editing
Refine your app by describing what you want changed. The AI reads your current code and applies a precise edit, then shows you the result. Keep what works, ask again if it doesn't.
Yours to own
Export the project as a ZIP or sync it two-ways with GitHub. Hand it to a developer, wire up CI/CD, or keep building in AppX. It's your app and your code.
Who it's for
- Founders validating an idea without hiring a dev team
- Designers bringing a mockup to life on a real device
- Developers skipping boilerplate to prototype fast
- Anyone who wants a working mobile app from an idea — and full ownership of the code
What's inside every app
- Framework — React Native with Expo Router for navigation
- Styling —
StyleSheet.create, the standard React Native way - Icons —
lucide-react-native - Local storage — AsyncStorage for data that persists between sessions
- Polish — haptics and blur effects where they make sense
Under the hood, generation and edits are powered by Google's Gemini 3.1 model family — but you never have to think about that. You describe; AppX builds.
