App Builder
Lay out your whole app. Then let your agent build it.
Screens on one canvas, connected by real navigation. One codebase for iOS and Android: Liquid Glass on iOS 26, Material 3 Expressive on Android.
Free to design, no account needed. Generating the code is the paid part.
What it does
A design tool that knows it is making an app. Not a picture of one.
- 01
Every screen on one canvas
See the whole app at once, zoom in to edit a screen, and drag blocks from the library onto it.
- 02
Arrows are navigation
Draw an arrow from a button to a screen. It becomes a tab, a pushed screen or a pop-up in the real app.
- 03
Preview before you build
Tap through the app the way it will run, switch between iOS and Android, and fix what feels wrong.
- 04
Hand it to your agent
One line to paste into your coding agent, which builds an Expo project with your screens.
Start from a template
Open the App Builder with an app already in it.
