BackTrack allows you to save your current location and then find your way back to it. It could be where you parked your car or maybe to help you find your campsite after a long day hiking. 

With BackTrack  you can save up to three separate locations and preview them in the maps application. You can then use the track functionality to guide you back to any of the locations.

The distance and heading to the selected location are shown along with your current heading and a big arrow which will point you in the correct direction when moving. Metric or Imperial units can be selected for the distance. A link to the maps application is also provided.

The accuracy of the current location is shown at all times, an iPhone 3G is essential for the best results.
