Useful long trail app
I am an avid backpacker here in NH and decided to section hike the long trail. The map that places like EMS sells does not have enough detail in my opinion, so I picked up this app as a supplement to my map. The maps are large downloads, but necessary since cell service is sketchy at best on trail. The app works great without any issues thus far. I really like its ability to calculate distances and elevation gains and losses by dropping two markers. I found this very useful when I had been hiking for a while and I wanted to know exactly what distance was left to the shelter or summit, etc... Battery life is still the biggest issue with using the iPhone on trail, however, if you take it in and out of airplane mode as you use it your battery should easily last 5 days.
