One of the best GPS apps for backcountry – GPS & Maps: Location Tracker Review

I’ve used this several times where AT&T coverage is poor or doesn’t exist. Being able to see where you are, have been and going is one reason to carry a ‘smart’ phone only instead of with a handheld GPS. Just be sure to download and update the maps for where you’re going BEFORE going ‘off the grid’.
