After a long search, I have decided for diesese device. Previously I had the probably identical Vifit of Medisana, but I did used only limited because the presentation and evaluation is only possible on the net. The recorded activity patterns gives a precise insight into the individual daily rhythm, I would like to publish in no way, finally takes place every few minutes in Germany a burglary. When XNFit the presentation and analysis software is supplied on a CD. In 24-hour clock, the activity is displayed graphically and numerically, the data can also be saved and are therefore available if required later disposal. The functionality corresponds to other activity tracker that recorded movement pulses are counted as steps and converted into distance and calories burned. Achieving self-specified targets can be read. For data transfer the device is plugged into a small adapter that is connected to the PC via a USB interface. Here, the battery is charged at the same time within a few minutes, the charging process is indicated visually. This operation should be carried out about once a week if you can still extend the interval, I have not tried yet. The small size and weight of the tracker and the practical clip shape animate to use the machine independently and without restrictions. Whether it is also waterproof, I can not judge. The device is practical and straightforward. Compared to its competitor models it stands out by its own evaluation capability and the excellent price / performance ratio. 5 points appear therefore justified to me.
