I've been using this progam on my 6210 Navigator for a couple of months now without any problems, it's set to automatically start each day and it has done so without fail. Definitely recommended, I'm hardly a fitness nut I just thought it would be interesting to see how much walking I do each day.

Pros: easy setup, automatic operation, restores data if the phone goes flat (has happened several times, it says 'One workout recovered after application crash' even though it was the phone that died not the app), very cool little graphs showing workout trends (even though I didn't discover them until this morning)

Cons: none that I have come across.
