Wrist rehab trainer: sideways phone grip auto-counts wrist reps, fully offline.
Wrist Trainer — your wrist rehabilitation training companion Wrist rehabilitation exercises don't need special equipment. Hold your phone sideways, perform wrist extension and flexion, and the app calibrates automatically and counts every rep — with training records kept only on your device. Features: • Automatic counting: the phone's motion sensors detect wrist extension and flexion; a rep counts after the target angle is reached and held; • Automatic calibration: hold the phone sideways, screen down, and stay steady for 3 seconds; • Adjustable target angle and hold duration; • Independent counts for both directions with haptic feedback and voice counting (English/Chinese audio); • Local session history to review progress anytime; • Interface in English, 简体中文, Español, Português, 日本語, 한국어 with light and dark themes; • Raw sensor data is never saved or uploaded. Account & Premium boundary: • Core offline training works without an account; • Some goal modes and Premium summaries require an app account with active Premium; • Price, trial eligibility, renewal, and cancellation are shown and decided by Google Play billing and subscription management — the app makes no promises. Device & measurement limits: • Requires a compatible phone motion sensor; • Results estimate the phone's relative posture and can be affected by device model, grip, whole-arm movement, speed, and sensor noise; • This app is not a medical device and offers no diagnosis, treatment, or medical advice. For wrist pain or injury, consult a doctor or therapist.
