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.
