Its display shows you the percentage completed on the program of the day and the time, and always very elegant way, like a flying saucer very high-tech. And in addition to your activity tracker, it also measures your sleep.
The details of your activity is obtained through the application on your smartphone (iOS or Android). Application which has also made much progress since its launch a little wobbly (android). And synchronization is done automatically dice the application is launched.
In practice, this tracker is revealed very satisfactory, although some times optimistic about its evaluations, but overall results comparable to its pre little things to another tracker worn concurrently, in order to compare them.
But you know, it is almost useless to talk about his performance in comparison, so its aesthetic tends to overshadow everything else. And we end up saying, after all we do not need an evaluation of the accuracy of the "death that kills", and in this case remains to compare its design, which admittedly is positively unique.
In summary, tracker extremely stylish, compact size of a 2 coin, battery operated button with a +/- 4 months of autonomy, its accuracy is quite comparable to that of other tracker on the market, and application that the driver is constantly changing. As for me, that's good, and God, it is beautiful.
maj: the rubber tab (or silicone) which allows to wear the buttonhole broke after 4 months. Disappointment, especially since his replacement is not given (more than 20 shipping fee)
