Well unless they sort Huawei Health out which I presume they will use for sync the health side of things will be useless again, What I mean by that is a step counter that counts steps from both watch and phone, no strava export, google fit and MFP export doesn't work, no counting BMR
Google fit sync rarely works and when it does it doesn't sync all the details. My fitness Pal does sync but adds an extra few digits to calories making it totally wrong I also forgot to.mention the watch doesn't track BMR only calories from exercise
Finally for me it seem to be working great. I take a 10 min walk to work each morning it records the activity, walk 10 mins home, it records that also, I do a 45 min weight session in the evenings and records that also.
