Built a posture app with Claude that mocks you on-screen for slouching
A developer with lifelong bad posture gave Claude one short brief and had it build a complete posture-correction app. The app uses AirPods to detect when the head tips forward into a slouch. The moment that happens, a pixel-art avatar of the user runs onto the screen with a sound effect and roasts them with a different message each time.
The overlay is click-through, so it floats over without blocking other work. It's built in Swift, and the entire app is essentially just this one alert-and-message mechanic.

- Uses AirPods to detect slouching in

- Roast messages vary each time
