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.

What’s New

Version 1.14

- This version fixes a bug related to accessing GPS information

No Data File

This app does not email the data file nor put it in iTunes using iOS 8. I have an old phone still using iOS7 and had no problem. In addition, the developer has disappeared along with his data file. Other than that, the app is exactly what I wanted.

You Made my day

Man, i suggest you to use the same export format of pocket imu app. It's easier to process with a spreadsheet and to produce graph for engineering paper! You have no idea how important is this app!
