I recently published an iPhone app called CoasterRider that tracks/maps Roller Coaster rides. You turn it on when you start the ride and then when you are done you get an animated map of your ride showing speed and elevation. The following promo codes can be used to get a free copy. Each code can only be used once, so it is only usable by the first person to use it.
Promo Code 1: F3F4FNRHRXT7
Promo Code 2: 9TNEWXXA3YL7
The application is called CoasterRider. You can preview it at:

The promo code can be entered in the Redeem button in iTunes.
