Joint Angle Camera vs Anglaxis

Joint Angle Camera uses your phone’s camera to estimate joint angles on the device, so you can check your movement during fitness, stretching, and teaching demos. Follow the on-screen guide, move through your range, and see a live pose overlay with approximate angles. This app is not a medical device. It does not diagnose or treat any condition and does not replace a professional evaluation. Angles are estimates and may be wrong. Use them only for everyday fitness and self-tracking—not for medical decisions. WHAT YOU CAN DO • Live pose overlay: keypoints and skeleton on the camera preview with approximate angle readouts • Eight body regions: neck, shoulder, elbow, wrist, waist, hip, knee, and ankle—each with focused movement modes (for example nodding, side tilt, arm raises, and knee bends) • Positioning guides: front or side facing cues and a silhouette to help you line up • Peak hold: keeps the highest estimated angle from a movement so you can compare sessions • On-device history: filter by region, movement, and side; edit pose snapshots; share a single-session PDF • Pro: mobility trend charts and session video with skeleton and angle overlays • Screenshots: save annotated preview frames to Photos • Privacy first: pose and angle processing runs on your device—no account, no upload of camera feed or biometrics FREE VS PRO Free: unlimited real-time neck and elbow estimates with positioning guidance, history, single-record PDF share, and the full notice & privacy policy. Pro regions (shoulder, waist, hip, knee, ankle, wrist): 10 free trials each; one-time purchase unlocks all Pro regions plus trend charts and overlay video. Billed through the App Store. TIPS • Use good light and a clear background; fitted clothing helps tracking • Readings depend on stance, occlusion, and image quality and may be inaccurate • Stop immediately if you feel pain or discomfort IMPORTANT This app is not a medical device and is not medical advice, diagnosis, or treatment. All angles are on-device estimates for fitness, stretching, and teaching only. Do not use them for medical decisions. Available in English and Chinese (Simplified); switch language in the app.

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.
