About
Papax Log Camera records video and field data together on your iPhone. Use it for field observations, road tests, equipment tests and experiments.
Keep the image and the data
• Record portrait 3:4 video with timestamps always visible.
• Choose overlays for GPS speed, altitude, accuracy, coordinates, route, attitude and pressure. Enabled labels appear in the preview and are burned into the saved video.
• Switch between your device’s rear physical lenses. Frame rates, stabilization and low-light options depend on the device and configuration.
Mark key moments
• Tap the flag while recording to mark a moment, or hold it to mark a range.
• Marker times and numbers are saved in the data file. On-video marker labels are optional.
Record, organize and export
• Choose GPS, fused IMU, raw accelerometer and gyroscope, and barometer data.
• Each recording includes a MOV video and matching .data.json file with frame times, sensor samples and quality information.
• Group and select recordings by date or batch, export them together, or save video only to Photos.
Local processing
No account, ads or third-party analytics SDKs. The app does not automatically upload recordings or sensor data to developer servers. Exports, sharing and device backups depend on your choices and system settings.
Important
100 Hz is the requested motion sensor rate; actual sampling and location quality depend on your device, permissions and environment. Milliseconds in a timestamp do not imply certified millisecond-level absolute accuracy. This app is not a navigation, safety-warning or certified measurement tool. Use it safely; do not operate it handheld while driving or riding.
