Recording modes for the IMU App

There are two collection modes when recording with the IMeasureU app: streaming and on board.

Streaming is ideal when instant information is required and the sensor is staying within a close proximity of the device it is streaming to. On board recording is ideal when a higher sampling rate is required and/or the sensor will not be within the proximity of the IOS device for part of the recording.

The details of the two modes can be seen in the table below:
