Auto rep counting for wrist rehab — hold phone sideways

2 followers

Wrist Trainer turns your phone into a wrist-training coach. Hold it sideways, screen down, stay still 3s to auto-calibrate. Do wrist extension/flexion — motion sensors track your wrist angle live and count a rep when you hit the target angle and hold it (no cheating by shaking). Separate counters, haptics, voice counting (EN/中文). Adjustable target angle, hold time, rep goals. History stays on-device; fully offline, no account. A training counter, not a medical device.
