For anyone who has a Sony Xperia Z3 (not compact) do you have a Fitbit band and app?

[AC Question]

I've been reading reviews recently about syncing issues but it was mostly with Samsungs. Just wanted to check if the band and app was working for you. I don't want to get one if there are syncing bugs with the Xperia Z3.
Just checking for Fitbit band and app. Not Lifelog.

My friend at the gym has both and hasn't had this issue, or at least he hasn't voiced his anger at it I see him using it most days in the gym.
