gpexe live app for iPhone and iPad

Using the gpexe live application the user is able to analyze the performance of outdoor sports looking at instantaneous values (speed, heart rate, power, vo2) and cumulative values (total distance, average power, energy consumption,...) of the athletes tracked.
The iPad Live requires the gpexe link, a specific hardware box that can be placed on the pitch for the real time tracking; it receives the data from the gpexe gps tracking devices - at 20 Hz, for up to 30 athletes - and it sends them to the iPads through a Wifi connection.
It is possible to create one or more concurrent sessions to group and compare many athletes in the same time intervals.
