4 stars: Only heart rate and sleep are accurate, exercise (walk or run) have a deviation of 10%, and blood pressure 25%...In sleep measurement, it measures from 21:00 to 8:00, I would like to have the ability to change this and also to calibrate the blood pressure measurement.
4 stars: somewhat confusing layout. Hard to believe po2 is at 99% at all times since I installed. Sleep is weird, I have yet to go to sleep and already it shows 34 minutes sleep time. Have seen sleep time as much as 1 hour while still up entertaining guests. New update, see what it looks like report back in couple days.
3 stars: I love the look of the unit, but the reason I bought this is because it said that th blood pressure was accurate. Far from it , it's way off...my bp is 134/85, and it reads 110/68...not very accurate. I have reset it and still no change.
5 stars: Only been using a short time but so far so good the blood pressure monitor and sleep monitor are awesome and tracks every step u take, loving this app, if you are having problems turn your watch off to see if that helps sync your watch and phone again it work for me hope this helps
3 stars: Needs improvements. Inaccurate at times. Android phone app doesn't synchronize well with Google fit. Using do not disturb mode works much better for swimming mode. Have to toggle Google drive setting and synchronize on home screen to download steps and time.
3 stars: It's ok except it's very innaccurate and dysfunctional and polit...
