HangSpine turns your Apple Watch into a dead-hang counter. Grab the bar and just hang — your watch's motion sensors detect the hang automatically and start the count for you. No buttons mid-workout, no phone needed. Every 10-second hold counts as one rep, confirmed by a haptic tap so you always know where you stand. WHY DEAD HANGS Dead hangs decompress the spine and shoulders after long hours at a desk, build grip strength, and stretch the whole upper body. A few minutes on the bar is one of the simplest full-body resets you can do. SMART DETECTION THAT ADAPTS TO YOU • Hang detection runs on the watch's gyroscope — mount the bar and the countdown starts by itself; dismount and it stops • Set your own pace: 10/12/15 s per rep and a daily goal you choose • An experimental on-device learning engine keeps learning your mount and dismount motion, so detection gets more accurate the more you train — no two bodies or bar setups are alike, and HangSpine adapts to yours. It's continuously improved and never affects everyday counting • Everything is computed and stored locally. Nothing is ever uploaded for training ON YOUR PHONE • Today's goal ring, streak flame, and day/week/month/year charts • 26-week GitHub-style heatmap of your training consistency • Trace viewer for every session: angle, X/Y/Z gravity components, and grip energy — see exactly what the sensor saw PRIVACY BY DESIGN All data stays on your devices.
