Local diagnostics for iPhone and Android
Use diagnostics in development to reproduce camera, rendering and tracking problems. For a controlled comparison, use the same marker or surface, camera distance, scene and sequence of movements on both phones. Record the browser, backend and performance preset with each run.
- Open the development diagnostics tool over HTTPS.
- Start one scene and let the camera settle before collecting a baseline.
- Repeat the action that causes the issue, such as covering the marker or moving the phone sideways.
- Export the report and identify the run by device and scenario.
| Observation | Signals to compare |
|---|---|
| Model stutters while marker stays visible | Render cadence, frame time, model complexity and device load. |
| Model jumps after occlusion | Target loss and recovery events, pose quality and marker size in frame. |
| Optical anchor moves with camera motion | Backend, initialization, parallax and relocalization. |
Development diagnostics use structured measurements. The public gallery omits the report controls. See camera and performance and odometry validation.
