Changing Accelerometer Sampling Frequency?

I just signed up and connected my iPhone to read the accelerometer data.
Currently, when I export the data I am only getting 3 reads/second. I don’t see anything within the application or documentation to retrieve the full 100 samples per second capability of the iPhone, so I was wondering if anyone has figured out how to do that.

@jlaro099 welcome to community.

How are you exporting the data?
