A Linux app that lets you know when you slouch. Optionally locks your screen when you step away.

Uses your webcam and MediaPipe pose detection to monitor your posture. When slouching is detected, you get notified to sit up straight (screen dimming or LED blink). Runs locally with minimal CPU usage - no accounts needed.
Install
uv pip install postured pip install postured
AppImages also available.
Requires notifications support on Gnome Shell.
Settings
Right-click the tray icon to access:
- Notification style - choose between screen dimming or LED blink
- Sensitivity - affects detection threshold; higher values trigger on smaller posture deviations
- Lock when away - lock screen when you step away from the camera
