The X4 ePerf Mobile App is used to manage the ePerf watch (ePerf Connect). It is an Android application. Each license can only be used once. (1 license = 1 android smartphone/tablet). X4 ePerf Mobile App manages up to 4 clocks (ePerf Connect) simultaneously with the same device. Imagine the use case of a bicycle race. The watch can be connected to smartphone #1 at the beginning of the race. At a checkpoint, the watch is connected to smartphone #2 and at the end of the race, the watch could be connected again to smartphone #1. All data is collected and merged.
