I use it now for more than 6 weeks, and it reliably provides data on my motion profile during the day and during the night (night use it however sporadically)
At first I was a bit confused about the difference to my running app (runtastic) until I got the tip to set the stride length better. You can define the default stride namely in the app. Of course, I do not always do the same steps (run, walk, climb stairs, etc) but the approximation succeeds very well now.
The design of the app I find intuitively simple and I have great fun with the motivation power of the small device:
when I think, wow what a day again passed his heels and then I see: hey, in fact there were only 3,000
Steps, then I walk in the evening and again going on, or ride my bike etc.
Some comments here in the reviews I do not understand; the Vifit does what he should, very good.
He does not claim even to have a GPS system (the accuracy of GPS systems I could write something,
my runtastic app displays each other a run length of the route, even though I always run the same distance ...)
, Comfortable to wear all class in all product, super maturity and a real motivation to move more.
