AT Thru-Hike (2015)

I thru-hiked the AT in 2015 which turned out to be the most amazing experience of my life and I did it with the Guthook App. I cannot recommend it enough for anyone planning to thru, section, or simply car camp the Appalachian trail. In my opinion, this goes on the list of "Don't leave home without it."

The AT, at least when I hiked it, was 2,189.2 miles from Springer to Katahdin. Frankly, if you get lost on the AT, you probably don't belong there. So the value of the Guthook App isn't navigation. The reasons I found it to be most useful was to alert me to the elevation that was ahead, distance to shelters and water sources, and road crossings that would take me into trail towns to resupply.

I used the Guthook App daily, but I also took along the AWOL AT Guide. I used this to a lesser extent, but I found it equally important. The AWOL guide is an invaluable resource for services along the trail (e.g., shuttles) and in trail towns (e.g., Post Office hours, lodging, etc.)

I hope this helps and best wishes on your hike.

"Today I begin a new trail in my life. A fresh start. A new beginning. Today I step off the rock at Springer to be transformed because I trust that it is only impossible dreams of this magnitude that will give birth to the type of change I covet." (April 1, 2015)

Developer has lost focus

This app was written to support backcountry hikers going long distances with minimal contact with internet. The current developer seems focused on a money grab of section hikers. Updates to the app break more than they fix (and we’re talking basic stuff like crashes and inability to look at adjacent waypoints). This ignores the obvious API misuse of basic features (CoreLocation use is wrong: blue bar should not show on exit; MapKit use is wrong: app should indicate its drawing an opaque base tile rather than asking Apple to download its own map only to be covered up).

Worse, the developer takes money for trails like the Te Araroa and doesn’t even bother to incorporate the freely available data in a way that’s actually navigable. As an example, the Trust notes (the basis for the trail) describe how to make it from on side of Rakaia River to the other. The gpx, however, does not include this because it’s not official. This, in turn, means Guthook/Atlas does not include a continuous footpath. The app is so stingy about providing base map data that there isn’t even enough detail to find it on your own, forcing you to use a third source of info (the Trust maps).

It might very well be worth your money to buy a trail because when it does work it’s quite convenient, but the app quality is in a downward spiral.

Seems to be missing a lot of info that is contained in other guides

After using this for a while on the AT, it’s become apparent that there is a lot of data out there on the trails and towns that is not contained in this app. I’m not sure where the app pulls data from, but it’s lacking in that department. Other guides seem to list more, and more current, data about available resources, like hostiles, restaurants, stores, etc. on the trail. And while the maps are nice, there are important waypoints that are just not listed. However they exist in other guides.

The app itself seems to run fine for the most part. I seem to experience an issue where the GPS stays enabled even though I turn it off in the app. The app shows the GPS off, but as soon as I move to the home screen (app in background) the little blue bubble in the upper left corner continues to indicate enabled. The only way to get it to stop is to force close the app.
