Know how much it did not in the day, this is still funny 5 minutes. Know how long we slept: same, knowing that it is sufficient not to move to the bracelet detects a deep sleep: not reliable at all, except perhaps for those jumping around as long as they are not asleep?
The alarm function does not convinced me: the bracelet vibrates, I go back to sleep in the second, and there is no reminder: argl! I have not found more effective alarm clock.
As for The application: it works by connecting permanently, galley when we didnt a good network and it is not available in iPad version.
This bracelet will not stay long on my wrist I think, I find it boring and unnecessary. The concept would have had a real sense if the heart rate was detected in addition eg, body temperature or any other interesting indicator and less empirical quune simple interpretation of movements. And if in addition we could show lheure of a simple click, it would be more useful. I do not even speak of course Bluetooth absence, we will say that this is to preserve the autonomy.
In short, a very incomplete product and, in my view, far too expensive for what this is.
