But now to the core of my review: Why should you buy it?
Since it will be difficult because the loop is alone from my perspective ziehmlich meaningless without heart rate monitor can be the daily calorie consumption using a calorie calculator simply errechen. As said above, this is exactly right plus minus 5 percent. If you want to have meaningful values have to make 1-2 week long sports with H7 / H6 Pulse Monitors. This one gets an average value at which one can orient oneself for his food diary like me.
In my opinion, a good activity tracker but mainly aimed at amateurs with enough money and sportsmen to professional athletes, said professional athletes hardly even considered how much he can eat exactly. Incidentally, all the pity is it about their money one can also borrow Activity Tracker, and as described above calculate an average.
