Insights
The trend sees what one session can't
A single sitting tells you little. Sixty days tell you when, where and for how long you lose your posture, and whether the change you made is working. Why sitting posture drifts over the day.

Common questions
AirPods Pro, AirPods 3rd generation and later, and AirPods Max. They need head tracking, and they need to be in your ears.
Yes. AirPods with head tracking report how your head moves and tilts. BodySignals reads that motion while you sit and walk, learns your own upright and measures how far and how long you drift from it. How posture tracking with AirPods works.
No. It doesn't hold you in place. It is a posture tracker: it measures how you sit and walk and gives you a quiet nudge when you slouch for a while. Straps and braces have little evidence for lasting change, see what the research says about posture correctors.
No. A walk starts on its own after ten seconds of walking, and a sitting ends when you stand up. You can still start one yourself.
Only as much as you ask it to. Choose precise, calm or off. Calm reminds you at most every 15 minutes, and nothing comes before a full minute past your own line.
It learns your upright in the first ten seconds of each session, so a new chair or a laptop on the sofa doesn't throw it off.
No. BodySignals reads the motion sensors only while a session is running and lets go of them the moment it ends, so your AirPods and iPhone last as long as they always do.
