Open HangSpine on your Apple Watch and tap Start. After a 3-2-1 countdown, grab the bar — the watch detects your hang automatically and counts every completed set. No taps needed mid-workout.
Keep still on the bar for 1–2 seconds after mounting — the watch recognizes the hanging posture via its motion sensors. Quick regrips (under 4 seconds) won't reset the current set. If detection feels off, see the adaptive detection question below.
Yes. In the iPhone app, tap the gear icon → Training to choose 10/12/15 seconds per rep, and set your daily goal under Goal. Changes sync to the watch instantly.
Everyone's body and bar setup are different. The experimental Feedback Learning feature records the motion trace of each session and periodically tunes detection to your personal mount/dismount pattern — entirely on your device. Enable it in Settings → Feedback Learning (Experimental), then review and label your traces under View detection traces.
Only on your own iPhone and Apple Watch — no account, no server, no tracking. An optional iCloud backup uses your private iCloud storage. See the Privacy Policy.
HealthKit access is optional — it only saves completed workouts to Apple Health. Declining it does not affect counting or statistics. You can change this anytime in the Watch app: Settings → Privacy & Security → Health → HangSpine.
In the iPhone app, tap the gear icon → Language. The choice applies to both the iPhone and Apple Watch apps immediately.
iPhone app → gear icon → Erase all workouts. This removes every session from the device and cannot be undone.
