You describe an app in chat and get a working React Native / Expo app you can open on your phone right away with a QR code. Unlike prompt-to-code tools that hand you whatever the model writes, every change runs through a deterministic check (type-check, lint, real build) before you see it. That makes the output an app that actually runs, not a demo. It also comes with the parts real apps need: database, auth, push notifications, file storage, in-app purchases and ads. It ships to GitHub and the App Store / Google Play through EAS. Available on the web and as a desktop app for macOS and Windows.
