The clock runs on Android, and was at first but very error prone.
The regular updates (1x a month), the errors were eliminated more and equipped the system with new features.
Also according to the official forum, followed by further updates.
The pulse belt from my Garmin Clock, supports such Motorola MOTOACTV
Since you can download on the clock and various cards, and the route that you have traveled too can look like on the screen, I would like to see a navigation function which simply could deliver in upcoming versions.
For the bikers would be optimal. While the display is not as great as with a standard GPS device, but just look for if you are on the correct path, as more than adequate.
For me personally, the clock is no longer possible to think. Did it every day, either as a normal clock or just when exercising.
For recreational athletes like me very useful.
