The app was working for a few days, but it wont pair up with Bluetooth through the app any more. Shame, was pretty good for a few days.
UPDATE
The app is still a little clunky, but it seems to be working now! After the initial install of the update, it the app seemed broken. When I deleted and reinstalled, all previous problems seemed to have been solved. The feedback button now works and doesnt crash the app, searching for the bracelet now works, and syncing seems to be faster. Much better product so far.
