Sensor Data Pro

Sensor Data Pro records every sensor of your iPhone on one precise timeline, together with video, sound, Apple Watch and Bluetooth sensors. Review, analyze and export your sessions for research, engineering, sports and field work.

RECORD
- Accelerometer, gyroscope, magnetometer and device motion, each at its own rate up to 100 Hz
- GPS and compass, barometer and altitude, steps and activity, sound level
- Keeps recording with the screen locked: when nothing else keeps it running, GPS is recorded at low accuracy (you can turn this off); anything iOS pauses is marked as a gap instead of being filled in
- Event markers with quick labels, countdown, auto-stop and presets
- Live Activity and Dynamic Island with Mark, Pause and Stop; Siri, Shortcuts, the Action button, Control Center and a widget
- Crash-safe: an interrupted recording is recovered the next time you open the app

REVIEW
