Dude, Where’s My Car? Smartphone App
The free iPhone app will keep track of the place you parked your car and it will direct you to it the same way the GPS in the car shows you the way somewhere. All you have to do is pin the location when you park and eventually add a note with, say the parking floor or parking spot number.
Other functions can allow you to see nearby gas stations, set parking meter alerts, view parking history or you can order a cab if you drank one beer too many.
The app will run on iPhones and iPads using iOS 5.0 or later, and you can download it from the official website for free.
