Basically I don´t know, if that topic was already discussed, but:
wouldn´t it be pretty cool, if Locus is showing me my burned calories (in kcal or kJ) after a trip, or even before???
All the main data is actually known:Locus knows:
length, altitude, speed, ...I know:
my age, my weight, ...
I know, that the calculation of burned calories is a little bit complicated and depends of a lot of parameters, but by using the upper data, it would be a first step...
