Answer 1

There have been many tests on how accurate the trackers are.  The trackers don’t do anything by themselves.  You don’t need a tracker to exercise.  

I’m not sure what kind of study you’re looking for.  Studies are typically done to test the effectiveness of X. 

Take 10 random people who want to get in shape.  Have 5 of them wear a tracker and 5 don’t.  The results will be based on the effectiveness of their exercise routine, not on anything the tracker is doing.
