Please include your iPhone model, iOS version, and the app version (shown at the top of the screen, e.g. v1.0.0).
Requirements
- iPhone with an A12 chip or later (iPhone XS / XR / 11 and newer)
- iOS 17 or later
- A reasonably well-lit room
Troubleshooting
No body is detected
- Stand 1.5 to 3 metres from the camera — full torso in frame.
- Plain clothing with contrast against the background works best. Loose robes or camouflaged backdrops can defeat tracking.
- Avoid strong backlight (bright window directly behind the subject).
- The first detection can take 1–2 seconds. Move slightly if it stalls.
Tracking looks off — organs drift or jitter
- Give the app its first second to calibrate to the tracked person's proportions. Accuracy improves after calibration settles.
- Keep the full torso and head in frame. Cropping either degrades the underlying skeleton.
- Side profiles and extreme yaw can confuse body tracking — face the camera where possible.
Muscles mode is slow or crashes
- Muscle rendering is the heaviest mode. On older devices (A12 / A13), toggle bones or skeleton off while muscles are on.
- Close other apps to free memory. iOS may terminate the app if memory is exhausted.
Camera or microphone permission was denied by accident
Open Settings → Corpus 4AR on your iPhone and re-enable the permission you need. The app requires the camera; the microphone is only needed if you want sound on your video clips.
