Hi! I just released my Car Locator app
Just hit a button to save your car location, and the app uses GPS and compass to navigate you back to your car using radar view/map view/split view. You can also see how long you've been parked for and set an alarm to ring after you've been parked for a certain amount of time. Now i know there are a couple other car locator apps out there, but this one, I believe is the best in terms of interface, features, and polish.
