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, then generates and validates React Native code. When the build is ready, you scan a QR code, open it on your own phone and test the result. Don't like something? Just say so in chat — "make the header dark," "add a settings screen," "the save button overlaps the keyboard" — and the edit is applied and the preview updates.

When you're ready, a real person from AppX helps you publish to the App Store and Google Play. You can also share a link or download the code.

How it works​

  1. Describe — "Build a habit tracker with streaks and a progress chart."
  2. Generate — AppX plans the screens and writes real React Native code for each one.
  3. Preview — Click Open on phone, scan the QR code, and see your app on your own phone in its browser (on Android, in Expo Go too).
  4. Refine by chat — "Make the button blue." "Add a dark theme." "Show a confirmation before delete."
  5. Publish — Send a store request from your project, and a person from AppX gets it into the App Store and Google Play with you. Or share a 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, not a faked-up simulator: scan the QR and it opens in the phone's browser on iPhone and Android, and on Android you can run it in Expo Go. Tap through it exactly as your users will. After an edit, reload it on the phone to see the change.

Chat-driven editing​

Refine your app by describing what you want changed. The AI reads your current code and applies the edit, and the preview updates. To go back, use Undo on the turn card.

Yours to own​

Download the full project as a ZIP on every plan. Put it on GitHub, hand it to a developer, 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

The message box has a model picker. Leave it on Auto and AppX chooses for you. You describe; AppX builds.
