Good idea but badly made
The good point is that it estimates well how much calories you use based on a cardio frequency meter. But it is badly written and requires a permanent Internet connection. It happens often that coming back from a run, fast walk or workout outside, when checking how many calories where used, the software just throws away the whole workout data with no possibility to recover it ever, just because it is not connected to the Internet at that precise moment
