The pill at the top of Home tells you what Posture Plus can see.
"No AirPods"
- Check that your AirPods are a supported model: AirPods Pro (any generation), AirPods Max, AirPods (3rd or 4th generation) or Beats Fit Pro. Other headphones don't report head movement.
- Connect them in Control Center or in the iPhone Bluetooth settings.
- Wear them in both ears. Motion comes from the AirPods you're wearing.
"Motion off"
Posture Plus doesn't have Motion & Fitness access. Turn it on in the iPhone Settings app › Posture Plus › Motion & Fitness.
The angle looks wrong
If your head angle reads high while you're sitting up straight, or low while you're slouching, recalibrate: Settings › Recalibrate neutral position. Sit tall, look straight ahead at eye level and hold still for three seconds.
Calibration says it didn't get enough motion data
Make sure your AirPods are in both ears and connected, then try again.
