Perfect for tracking I used this to track my travels through Morocco. It worked perfectly even without any cell or data service available. The interface is super intuitive. The only drawback I have noticed is the times displayed on import into Google Earth  but I'm not sure if that is an issue with Google Earth or the app. The times displayed are adjusted for the time zone difference so if it was noon in Morocco when I was doing something  the Google Earth display will show it as 4am. A bit annoying but not a huge deal.
