Step Doctor turns your phone camera into a walking and balance lab. Record a short video and AI gait analysis measures how you walk, stand up and keep your balance — no sensors, no wearables. THREE MOBILITY TESTS IN ONE APP Gait analysis (walking test) Walk toward the phone and get gait speed, cadence, step length, step time, stance and swing phases, left/right symmetry and a 0-100 gait score. Timed Up and Go (TUG / iTUG) The classic stand-up, walk 3 m, turn and sit-down test. Step Doctor times it automatically and splits it into phases — stand up, walk, turn, walk back, sit down — so you see where the time goes. SPPB (Short Physical Performance Battery) Balance stances, a gait-speed walk and five chair stands, scored 0-12 on the standard SPPB sheet, plus a balance quality score. WHAT YOU GET - 3D replay of every walking test from the video, no face shown - Trends, calendar and history for gait speed, cadence, balance and TUG time - Shareable PDF reports for gait, TUG and SPPB - Ask the AI assistant what your results mean - Works on Android phones and tablets WHO IT'S FOR - Older adults and families keeping an eye on walking, balance and mobility - Physical therapists, rehab and senior-care teams who run TUG, SPPB and gait tests - Anyone curious about their walking pattern and steps Made by AICU.
