General GPS Trails Info

Not an iPhone user? GPS Trails is also available for Android phones. Check out for more info.

Note: Backpacker GPS Trails is designed and optimized for the iPhone 3GS or 3G. The 1st generation models lack a GPS chip required to run the application.

Battery Life: While we optimize our code to cut down on power requirements, continued use of the GPS running in the background can dramatically decrease battery life. For longer dayhikes or overnight trips, we suggest packing backup battery packs to charge the phone.
