I would like an app like this in the event I ever need to prove my location. And I think it would be cool to see where I go on a map.
If you've got the right version of android and the right settings, go here: https://maps.google.com/locationhistory/b/0

But, all joking aside, "For the increasingly few of us who haven't used a Google account on a smartphone (or who currently haven't signed in), what you'd be looking at is your Location History plotted on a map. Unless you've actively taken steps to stop it, Google has been automatically recording of your location every 45 seconds and time stamping each coordinate." [0]
