Another great feature is that you can perform on an app on the smartphone the evaluations using Bluetooth.
Has worked at my HCT M8 without problems only occasionally need one 1-2 try it isolates itself.
I find it a pity that the data stored on the tracker can not be deleted manually. As I have found on the Help page, they are automatically deleted every day at 24:00 clock. The Synchronizing always occurs in 15 min. Blocks, ie not be surprised if after eg 5 more minutes are displayed on the app no new results.
The tracker you can switch to sleep mode in the sheep, then he records the activity in his sleep auf.Was times completely Interesand is, I do not think it is abe as accurate.
Overall I am very satisfied with the tracker - it's really fun to look at the evaluations and a motivated to do more steps
If you have taken any interest in such a great device, Medisana has an online store, where you can buy the Vifit not only, but another article (eg scale, blood pressure monitor, etc ...) which you can also connect via Bluetooth ,
