This app was developed for researchers so that they may capture accelerometer, gyroscope, and magnetometer data directly from their iOS device to use for research or play around with. The data is time stamped and the data from Apple's enhanced device motion is included for reference.

Amazing Potential

As a recording mechanism, this app has some incredible potential. It could really benefit, however, by offering the user a way to adjust the sampling rate (i.e., takes a reading every 15 milliseconds or 2 seconds or 9 minutes). Otherwise, the saved file just ends up being huge. That would easily make this a 4 or 5-star app!

App is not functional

Purchased app for a dollar then realized it doesn’t work. I cannot click the record button or anything else in the app. Waste of money

Says it collect data, but delivers something a little different

1) App Does not seem to show up in Settings.
2) App is not collecting GPS data.
3) App output CVS data has unnecessary data:
Want as follows:
Timestamp, Accel_X, Accel_Y, Accel_Z, Gyro_X, Gyro_Y, Gyro_Z, Mag_X, Mag_Y, Mag_Z, Lat, Long

Gyro should be rads/sec.

Developer Response ,

Please make sure that location services are enabled for the app.
Also, feel free to modify the data in the CSV file to units of your liking.
