Well, I would be satisfied if the altitude information would be only used for the diagram and not for the distance calculation. The thing is, if you use MeeRun for hiking or mountain biking, you usually have a strong interest in knowing the altitude profile you have mastered. So please include that in one of the next releases. MeeRun is almost perfect for me, the only thing that is missing is the altitude information...

I think a good way to get very accurate altitude information would be to look it up on some geographical data servers on the internet using the longitudinal and lateral coordinates. This could be done after finishing the recording of the track in order to save battery life. However, the downside of this method would be that the vertical position is always fixed to the ground... I think it would make sense to implement an option so that the user can choose whether she our he wants accurate altitude information or unbound vertical position logging!
