If you're into this kind of tracking but don't necessarily want to go with Google, check out the Moves app (available on both iOS and Android). It's pretty no-nonsense and has an API. It guesses at locations based on things that FourSquare has, which would be its main weakness compared to this, I think. Also, I'd be remiss if I didn't point out that one of the things that I love that uses the Moves API is Gyroscope (http://www.gyrosco.pe http://www.gyrosco.pe). Development seems to have stagnated a bit, but it's still a really neat site.
