- Comfortably on your wrist, not a chirp at my Armbehaarung despite "rubber band".
- Heart rate and pedometer function very plausible and give fairly accurate values on whether on display or in the app.
- The calorie counter is more like a mathematical problem, because the app / the tracker goes on the size, weight and movement. Blood tests are more accurate since.
- The app is really very thoughtful, very intuitive (iOS) and it's fun, they fill regularly with the data, such as fluid intake, food intake, goals that you have set for yourself - it then acts as a sort of incentive when the Tracker synchronized with the app.
- Pleasant vibrating alarm that awakens or notify you when an incoming call (if you are permanently connected via Bluetooth) one or one has reached his goals, is well felt and yet so unobtrusive that, as in my case, the woman is not from alarm clock wakes, but only to himself.
- Easy to read clock, which can be adjusted at will, with date, no date and and and .. Tapping will appear on the tracker the time or what you want to see, if you set it on the App.
- The only drawback that I'm missing is the "Smart Alarm" that the bracelet one awakens in a restless sleep phase and not to set the time, because as you can still be in REM sleep.
Perhaps coming soon with an update, because to learn the tracker might be less of a problem.
Otherwise, a strong buy recommendation, when you think about a fitness tracker. And one should quietly investing 20 more and the "Fitbit batch HR" instead of the "Fitbit Charge" buy, because the HR has a proper watch band and not just a button which makes a very unstable impression.
