Read full description

Praxis turns any phone video of a movement into a structured biomechanics report โ€” no wearables, no markers, no lab. Film a squat, deadlift, jump, sprint, or sport skill. Praxis reads the movement from the video and returns a clear breakdown: what's working, what to fix, and why โ€” in language matched to who you are. WHAT PRAXIS MEASURES โ€ข Joint angles and range of motion through the full movement โ€ข Rep timing, tempo, and velocity โ€ข Left/right symmetry and compensation patterns โ€ข Jump metrics โ€” flight time, contact time, reactive strength โ€ข Sprint and change-of-direction mechanics โ€ข Coaching that ties each cue to the data behind it BUILT FOR HOW YOU TRAIN โ€ข Athlete โ€” performance-focused cues and programming direction โ€ข Coach โ€” per-athlete profiles and roster-ready summaries โ€ข Clinician โ€” structured, terminology-aware movement observations โ€ข Everyday โ€” plain-language guidance to move and train better HOW IT WORKS 1. Record or upload a video (single phone is all you need). 2. Praxis extracts pose and computes the metrics on-device. 3. You get an instant, readable report with prioritized coaching. Optional two-phone capture adds a second angle over your local network for a fuller 3D picture. LiDAR and high-frame-rate capture are supported on compatible devices. PRIVACY Your videos are processed to produce your analysis. You control what's saved, and you can delete your account and associated data at any time from Profile.
