Build with AI

Describe features, screens or changes. Open App works directly on your project.

Add a calendar view and keep the interface clean and minimal.

I'll update the screens and keep the React Native project in sync.

02 / Shape the UI

Shape the interface without losing control of the underlying project. Generate a new style and watch every component adopt it instantly.
