Hmm, today, i used meeTrainer and Endomondo (on my old N79) simultaneously. MeeTrainer reported, that i went 8.39 km whereas endomondo "said" that the distance was 8,83 km. I think, it's a good and sufficient result and pretty similar.

But i think, that i discovered a bug. I was doing another hike today and after a while, i paused meeTrainer, because we went to a hut to eat something. After that, i resumed the tracking. At the end of the route, the app displayed the total walked time correctly. But when i opened up the Workout section, the duration shown was only the time (in my case half an hour) i walked AFTER i resumed the tracking. Maybe the app uses the wrong variable to save the time in the Workout section?!
Can you reproduce this or confirm it ?

Cheers
