Footprints Is an Energy-Saving Location Tracker for iOS

Like Google Latitude (and other apps), Footprints tracks your location and shares it with others so you can find your friends or track your kids. What Footprints does better is provide easy sharing, less drain on your battery, and the ability to report your location to multiple sources.

While Footprints can eat up as much of your battery as Google Latitude (and others), it allows you to set the interval for when your location is reported so it reports less and therefore uses less of your battery.

Sharing your location is also very simple, as you can sync up with Facebook or just select someone from your address book who’s also using Footprints.
