Radar: Finding Your Way Back
"A must-have application for parking, going to the countryside or travelling abroad...If you leave a place and want to return there later, just turn Radar on and select the place with one click. Then, when you want to go back, turn Radar on, and it will show you the way."
My wife has this habit of turning on the car alarm when finding our way through a parking lot back to the car - with this app, you'll be spared some odd looks. With Radar, you can mark the place you want with GPS, and it'll let you know what the direction and distance are to get back. Of course, us guys don't need such help right? If you're still interested though, Radar's available for $0.99 through the Marketplace.
