has anyone been using smartphone tracking applications? I have been using endomondo for the fun of it

this weekend I will try out: http://www.mapmytracks.com/ it looks as if it could be more sailing friendly than endomondo.

when the smartphone is connected to the boat's sound system, endomondo announces total nautical miles covered as well as the time it took to travel the last nautical mile, this has kept me awake on overnight cruises
