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.
BUILT FOR
Coaches, athletes, physical therapists, athletic trainers, and movement researchers who need fast, repeatable 2D video measurement in the field or the clinic.
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.
