Turn your iPhone into a frame-by-frame movement lab
Anglaxis measures joint angles, range of motion, and AI-assisted sport mechanics — frame by frame, right on your device. Built for coaches, clinicians, and researchers.
Requires iPhone with iOS 18 or later.
Measurement you can trust
Precise digitizing tools plus AI that does the first pass — so you can verify, not start from scratch.
Angle & distance tools
Freeze any frame and place 3-point angles, distances, and paths. Zoom-to-digitize precision with fine handle adjustment for research-grade point placement.
AI auto-angle
Tap a joint and on-device Apple Vision pose detection places the angle for you, with a confidence score. Every AI estimate stays fully editable.
Angle over time & ROM
Track a joint across an entire clip to chart its angle over time and compute range of motion, peak flexion and peak extension — then jump straight to those frames.
High-frame-rate capture
Record at up to 120/240 fps and review in true slow motion with frame-accurate stepping and a graduated scrubber.
Annotate & voice memo
Draw, label, and attach voice notes to specific frames. Compare two frames side-by-side to see change across a movement.
Private iCloud sync
Your projects sync through your own private iCloud database. Video analysis runs on-device — clips are never uploaded to Anglaxis servers.
Sport performance analysis
Record or add a clip and Anglaxis auto-detects the filming plane — side-on or front-on — and applies the matching analysis.
Metrics include hip & knee range of motion, pelvic drop, dynamic knee alignment, elbow and shoulder motion, trunk lean, and hip–shoulder separation — each shown with reference guidance you can benchmark against your own norms.
