Very useful For knowing how long until next water, campsite, etc. This said, one should not rely on it exclusively, and many of Guthook's campsites are overused or out of compliance with FS regulations. Make sure you know what you're doing out there!
Worked great until I got close to yosemite I had it working in offline mode at home before the trip. Guide looked great with campsites and water indicated on the trail. Then as I got close to Yosemite the map guide stopped loading and at best was a basic GPS device. I tried uninstalling and reinstalling, shutting phone off and on. It's much too buggy to rely on and a waste of $10
Needs update and fixes Facebook test post fails and crashes app. Also app optimization on my s6 edge plus flags this app as using a huge amount of battery and resources and to uninstall.
Awesome app! Very helpful on the trail!
Guthook's JMT guide Trail map for use on your cell phone. Using a solar charging system, I kept my phone charged so I could use this guide. It is very accurate. The only time we had a problem was when the guide said there was water at mile 200 near the camp site. We had to go an additional 4 miles to find a good water source near a camp site which was at Crabtree Meadows. Or go back about 2 miles to a large creek. It appeared that there was water at mile 200 previously. This is a great app to use while hiking the JMT.
Worth the price, but not perfect Was quite useful on my recent JMT hike. One major bug was irritating: There was no way to switch between topo and satellite maps, and sometimes on the same scene one panel would be topo and one adjacent panel satellite. Irritating. Would like to be able to add campsites, bear sitings and comments without logging in, to be uploaded when I got back home. I would like to be able to view selected points on the altitude graph, instead of only my current position.
