For Sport: yes, for the home: no

When walking it measures (if you have entered the body size) the distance amazingly accurate. Even the pedometer works then great. The "monitoring" of sleep is more of a gimmick - at the end of the night zählts how you feel :)

Big problem: Almost all activities at home (showers, hair blow-dry, washing hands + -abtrocknen, brushing) climbs the pedometer suddenly abruptly in utopian heights.
Ex .: When you wake up I had 30 steps on the "speedometer". 20 steps to the bathroom there to get a little fresh. Suddenly warens already 200 steps. Once showers? Again 60 steps. Brushing? +50.

Unfortunately, errors have (for me?) So strong cumulated that the measurement uncertainty is too large.

With a heavy heart is the smart vivo therefore back.

The battery lasted for over a week by the way (would determined 10 days has come with it)
