3D Motion System
Your movement drives the KOA avatar.
No wearables needed. Camera capture, 3D skeleton recognition and real-time correction — every rep is seen.

Zero hardware
One phone is enough — the camera tracks full-body movement. No bands, no sensors.
3D skeleton recognition
Key joint angles parsed frame by frame. Squat knee paths and bench-bar paths, made visible.
Real-time correction
Short range, drifting path, shaky tempo — flagged on the rep it happens, not in tomorrow's recap.
LIVE training mode
Sets, reps and joint angles on screen while you train — like a coach counting every set with you.
