Joint Angle Camera
Read full descriptionHide full description
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.

Verdict
The clearest difference is in-app purchases: Nirvana Infared NJ at none against Joint Angle Camera's 1. Joint Angle Camera's advantage is update cadence (every 3 weeks vs every 3 months). On price, ads, device support and iOS requirement there is nothing between them.
