It is a pity that there is no list of compatible devices.
Then it must be said that the application itself is not super well developed. In fact, it is common to all devices Beurer. So when launching the application, we are a bit surprised to see a whole lot of features (weight monitoring, voltage ...). I thought for a moment that the watch allowed to do it all !! But no, this is in case you would connect another device.
Well, we must say that the documentation is extremely low, virtually non-existent. Finally, the operation is very simple, but it's a bit confusing at first!
What I also criticizes the application is that it is not intended for multi-user use. One can well imagine that in a family lends this watch to check the sleep from time to time, for example. You can create multiple accounts on the application, but the watch itself does not support multi-user, so everybody gets the information to everyone!
I am a little skeptical about the quality of data on sleep. I feel that it may consider that we are in deep sleep, only if we remain absolutely still at least 10 minutes straight.
Finally, I developed an allergy to the wrist in contact with the watch. So I had to stop using it. If you have sensitive skin, you should know that the material can be allergenic.
