About
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
