Acc.elerometer
Record sensor readings
Free · Designed for iPad. Not verified for macOS.
Record motion on iPhone, iPad or Apple Watch. Send watch recordings to your iPhone, explore charts and export sensor readings as CSV
See how your device moves with Acc.elerometer. View live sensor readings, record an experiment and examine the results on your iPhone or iPad. Capture motion on Apple Watch and send recordings to your paired iPhone for charts and CSV export.
EXPLORE SIX MEASUREMENTS
- Acceleration, including gravity, in G
- User acceleration, with gravity removed, in G
- Rotation rate around three axes in rad/s
- Magnetic field in microteslas
- Device attitude: roll, pitch and yaw in radians
- Gravity along each axis in G
View individual axes and vector magnitude where supported. Follow changing values and review recorded measurements to explore movement, rotation and orientation.
RECORD AND REVIEW
Choose the measurements you want to capture, then start and stop a recording. On iPhone and iPad, set the measurement interval from 0.1 to 1 second. Open saved recordings to inspect charts, switch between individual axes and vector magnitude for supported measurements, and identify gaps in the data.
EXPORT YOUR DATA
Export each measurement from a recording as a CSV file with timestamps and axis values. Choose Unix time, spreadsheet serial dates or formatted date strings for your analysis workflow.
CAPTURE MOTION ON APPLE WATCH
View sensor readings and record selected measurements on your wrist. Send saved recordings to the paired iPhone and follow transfer progress. Add watch face complications to see saved sensor maxima or recording status, and open the app to start a recording from the recording widget.
FOR EXPERIMENTS AND EVERYDAY CURIOSITY
Explore device motion for a physics demonstration, a development project or your own experiments. Measurements and recordings are stored on your devices. No account is required.
Available readings and actual sampling intervals depend on the device and its sensors. Apple Watch recording duration is subject to watchOS background runtime limits. Watch complications show saved values from the app, rather than a continuous live sensor feed.
- Added an Apple Watch app with live sensor readings, detailed axis values and recording of selected measurements, including background recording within watchOS runtime limits.
- Send saved watch recordings to your iPhone for chart review and CSV export, with transfer progress and import confirmation.
- Added watch complications for saved sensor maxima and recording status, with a shortcut to start recording.
- Periodic saving and recovery of saved data help preserve interrupted recordings on iPhone, iPad and Apple Watch. Interruption warnings show when a recording may be incomplete.
- Charts highlight gaps in recorded data and let you switch between axes and vector magnitude for supported measurements.
- Improved chart sampling to keep readings in order and preserve the final sample.
- Added Russian localization for the iPhone and iPad app, Apple Watch app and watch widgets, including sensor descriptions, chart labels and transfer errors.
- Recording times now follow the regional time format, and date formatting correctly respects the supplied time zone.
- Updated the app icon.
