This app has become the Gold Standard for thru hikers. The good is that it can keep you on the trail, even when no real trail exists. Also really useful in snow. The bad: We have found errors in some cases on the actual trail location (both CDT and PNT). The errors were usually obvious enough to ignore the app, but may make you pause to figure out the error. Since the errors are reasonably rare, I can give it a 4/5 stars. Additional thoughts: The input from other hikers is invaluable, so its a part of the app it is in your best interest to get familiar with. Finally getting help from their staff is great, when you do run into technical difficulties.
