The app always hangs on "sync..." I watched it for 10 minutes and never competed.
While syncing you cant change settings so its really annoying as you have to randomly hope you get lucky.
The first day my data loaded but never again. Everyday I can see my steps for the day immediately but tomorrow they will have disappeared and never go into health kit.
Sleep never shows anything despite being set.
Bracelet itself is solid but the app is useless.
Tried on two iPhone, updated firmware on band and same result.
