Has anyone found any cases or bands for the Fitbit Sense that have structure that helps to hold the device appropriately against the skin during workouts?
I have tried a number of different bands with different tightnesses and positions on each of my arms, and cannot get the Sense to consistently get accurate heart rate measurements during active exercise (especially bicycling and rowing; running seems to work somewhat better).
I've seen lots of other people with this issue in this forum, but haven't seen any good solutions.
My theory is that the optical sensors on the device don't work well if the contact with the skin is inconsistent or too tight or too loose, and I am wondering if a case that was designed to help ensure consistent positioning might help.
Maybe something rubbery/silicone with some thickness "under" the Sense between the device and the skin to hold it with a consistent gap/pressure?
Or has anyone found any homemade / 3D printable designs for cases/bands that might be customizable to do this?
Thanks!
