Introduction to AppX

Describe an app. Generate real code. Test the result on your phone.

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 and validates React Native code, and gives you a QR code when the build is ready. Scan it with Expo Go and test the result on your phone. 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 the accepted update land in the preview.

When you're ready, publish to the App Store and Google Play, or share a link.

How it works​

  1. Describe — "Build a habit tracker with streaks, reminders, and a progress chart."
  2. Generate — AppX plans the screens and writes real React Native code for each one.
  3. Preview — Scan a QR code with Expo Go and see your app live on your phone. Changes show up in seconds.
  4. Refine by chat — "Make the button blue." "Add a dark theme." "Show a confirmation before delete."
  5. 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.
