Where's my car?

You parked somewhere near the stadium, but when the concert ends you don't have a clue where the car is. The friends you came with are equally as clueless.

Fortunately you haven't lost your Android phone that never forgets anything, and you remember you have the hot new app, Android, Where's My Car?. With this app, you click a button when you park your car, and the Android uses its location sensor to record the car's GPS coordinates and address. Later, when you reopen the app, it shows you a map from where you are to the remembered location-- problem solved
