In this video I’m showing you the easiest way I’ve found to create high-quality mobile app UI/UX before you write a single line of production code. It doesn’t matter if you’re building in Flutter, React Native (Expo), or even native Android/iOS—the workflow is the same: generate a full set of screens, visualize the entire app flow, and prototype navigation so you actually know what you’re building. And just to be clear, this is not sponsored. I’m sharing it because it solves a real gap I keep seeing with web-based AI app builders. I use vybes.dev to generate complete UI flows (onboarding, auth, main screens, subpages, settings), then I link screens together and test everything in prototype mode. The key difference versus tools like Bolt or Lovable is you can see every screen upfront and control navigation instead of blindly getting a “prototype app” you can’t realistically ship to mobile stores. Once the screens look right, I open any screen, hit “copy prompt,” choose Flutter or Expo/React Native, and paste that prompt into Cursor (or any AI code editor). Cursor then implements the design as native code—colors, spacing, typography, buttons—so you can ship real builds instead of stuck-in-the-browser demos.
