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 - Synced multi-track timeline with zoom, map and per-axis statistics - Events and gaps on every track - Export to CSV and JSON, and import sessions shared from Sensor Data Pro The free version records up to 15 minutes per session. PRO+ - Unlimited recording length - Video synced to your sensor data, and audio files you can play back on the timeline - Apple Watch heart rate and wrist motion, with start, pause, mark and stop from the watch - Bluetooth heart-rate straps (with RR intervals), cycling speed, cadence and power, and running sensors - AirPods head motion and ARKit position tracking - Live streaming to your computer over UDP, TCP, WebSocket, HTTP, MQTT or ROS 2 - iCloud sync between your devices - Spectrum, spectrogram and filters for every sensor and for the recorded sound; compare sessions, trim and split - MCAP for Foxglove and ROS 2, GPX, KML and GeoJSON routes, and whole session packages to share - Threshold triggers and unlimited presets Pro+ is available monthly, quarterly or yearly.
