Will BB10 run an Android versions of activity tracker apps?

I have a Z10 and want to get an activity tracker, such as a Fitbit or Basis. I haven't had any issues running android apps so far but was wondering if anyone has been successfully running anyone's proprietary android app. I'm running 10.2 and have not installed a leaked 10.3.1. I assume android compatibility increases in 10.3.1. Thanks.

10.3.1 vastly increases support to android APPS but not quite as much Android WEAR.

I'd take my device to the store and test there, but don't keep your hopes up.

My fitbit one syncs with the android app perfectly. Using a Z10 with SR 10.3.1.747
