We all know what it is like to drive somewhere unfamiliar and forget where we parked our car, or to take a day trip to an amusement park or other place with a large parking lot, park, and leave your car all day only to forget whether you parked in G-5 or 5-G. If you have an iPhone with iOS 4.0 or later, G-Park is an app that can make sure you never have that problem again.
