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.

Bugs and requests

nRF Connect for Mobile

Reported bugs

4 issues
  • Can't read data from Bluetooth device
  • Tries to ask for Bluetooth connection when Bluetooth is off. Asks to connect to devices when Bluetooth is off. Who knows what this app is doing in the background without permission?! What ever it is , it ain't good
  • Tapping "tabs" doesn't work (nothing changes in the UI). To get some response from tapping UI controls typically requires (a) launching nRF Connect, (b) switching to another app, (c) switching back to nRF Connect. I've tried uninstalling and re-downloading. Same result. This used to be the bee's knees of BLE tools but it's only worth 1 star at the moment (v2.7.11).
  • Cant go past the initial announcement. The app is unresponsive to the taps.
