I'd be interested to know ultimately how much memory this is going to use. If you look at the actual data, it's taking data captures every minute or two and saving them in a log that goes on forever. And mine has only been tracking data for a few days. Health app is showing it only takes up 2.2mb so far, but I wonder what this is going to look like in a year if it saves it all. I can't seem to manage storage in the health app through settings.
