Everything you need to sit better
Live Silhouette
See a color-coded outline of your body. Green when good, amber when fair, red when poor. Your face is never shown.
6 Body Metrics
Tracks neck angle, head forward, CVA, shoulder slope, head tilt, and slouch — updated every frame.
Posture Score
Get an overall score out of 100 that updates as you work. See exactly how your session is going.
Sound Alerts
Gentle audio nudges when your posture has been poor. Toggle on or off anytime.
Coaching Tips
Actionable advice like "tuck your chin" or "level your shoulders" based on what's actually off.
100% Private
