With this application you can store the location of your car, via GPS, after it has been parked and then to help you in find it.
After all:
* You store the position of the car
* On the way back, ask to the application to locate your car
* Application will show you your position and that approximate one of your car (or of another mean), suggesting you the way to walk.

Disclaimer:
The purpose of the application is to help the user to find the location of the car, but it isn't the absolute instrument to find it.
The location storage depends on the gps data, wifi networks ... and it is not always right.
