Steps aren't tracking correctly. I've actually counted steps and Withings is short at least 10% or more. As well the syncing is frustrating me. My watch says 3500 but even though the app says it's syncing or connected it doesn't update the step count on my phone. The battery percentage has been wonky at times, fluctuating up and down. Honestly, I've come from a Galaxy tracker to this product and quite frankly thinking of going back to a Galaxy or nothing at all.
What gives with the sleep tracker. When I wake up I sync the app with the tracker, adjust any times needed and then do some reading in bed, which it adds as sleep onto what I've adjusted manually. So frustrating.
And to put icing on the cake my Withings scale went bonkers this morning! At least I can delete the entries in my app.
DO NOT BUY A PULSE HR! Between the list above, the breakage that is happening (yes a friend of mine has had to return his) and the very poor customer service, look elsewhere for a product
