Hunch notices slouching with compatible AirPods, your iPhone’s front camera or both, then gives you a gentle nudge to adjust.

Notice the drift. Make a small adjustment.
Made for work, study and everyday screen use. Hunch checks in on your posture, so you don’t have to remember to.
Step 1
Calibrate
Sit or stand upright, then tap Calibrate. Hunch saves this as the baseline for recognising changes in your posture.
Step 2
Track
Start a session and see your posture live. The face mirrors your head position and changes colour as you drift.
Step 3
Reset
When you slouch, Hunch nudges you with a sound, vibration or notification. Return to your starting position until the face turns green again.
Track with what you already have.
Use compatible AirPods or Beats, your iPhone’s front camera, or both together.

Uses the motion sensors in compatible AirPods and Beats. Hunch shows whether your connected headphones support tracking.
