Awesome app!

Used this (along with the paper map) on a 35 mile loop out of duck pass. It flawlessly pinpointed my location all but one time. It seems to have "Island Crossing" on Fish Creek Trail located in the wrong spot. I almost crossed on a log when up ahead about .25 mi there was a bridge. Other than that mishap it was so great to know exactly where I was on my hike.


I highly recommend this and the Yosemite app for anyone exploring this beautiful area. Had a really great time navigating using the detailed maps, and I'm looking forward to using them again.


Finally, a quality hiking app for Tom Harrison's trail maps. Love how the designer included every hiking feature possible with the download.
