Anglaxis turns your iPhone into a frame-by-frame movement lab. Record or add a clip, and measure joint angles and range of motion with research-grade tools — for sports performance and clinical movement analysis. SPORTS PERFORMANCE ANALYSIS Pick a sport, record or choose a clip, and Anglaxis automatically detects whether you filmed side-on or front-on and applies the matching analysis: • Running — hip and knee range of motion, pelvic drop, dynamic knee alignment • Cycling — knee angle at the bottom of the stroke, knee ROM, hip angle • Walking gait — hip and knee ROM, pelvic drop, frontal-plane alignment • Baseball pitching & hitting — elbow and shoulder motion, trunk lean, lead-leg block, hip–shoulder separation Each metric is charted over the whole clip, with peak values and a tap to jump straight to that frame. PRECISE MEASUREMENT TOOLS • Freeze any frame and place 3-point angles, distances, and paths • Zoom-to-digitize precision with fine handle adjustment • AI auto-angle: tap a joint and on-device pose detection places the angle for you — fully editable • Per-video real-world calibration for true distances CAPTURE & REVIEW • Record at high frame rates (up to 120/240 fps on supported iPhones) • True slow-motion playback with frame-by-frame stepping and a graduated scrubber • Draw annotations and attach voice memos to specific frames • Compare two frames side-by-side to see change across a movement CLINICAL LIBRARY Reference protocols organized by condition — the movements to capture, the plane, the camera setup, and which tool to use. General reference only; apply your own validated thresholds. PRIVATE BY DESIGN Recording and movement analysis run entirely on your device using Apple's on-device frameworks — your clips are never uploaded to Anglaxis. Enable iCloud to sync your projects across your own devices through your private iCloud account.

IMPORTANT Anglaxis is a measurement and decision-support tool. It is not a medical device and does not diagnose, treat, or prevent any condition. AI estimates from 2D video are a screening aid — always verify measurements and apply your own professional judgment.
