So, I didn’t know this: you don’t need cell service to use your phone as a GPS device — a very good one, in fact — provided you download the maps you need ahead of time. http://www.adventurealan.com/iphone-gps-map-backpacking/ Good article, lots of info. Maybe too much info? Turns out there are a ton of apps for backcountry navigation. Just about all are subscription-based, and I don’t want to sign up for all of them to choose a go-to. Does anyone have recommendations for a backpacking GPS app? EDIT - Well, I went ahead and subscribed to GAIA GPS Premium with the discount link in the article. Will share thoughts on the app when I’ve been able to give it some real world use. I’d still like to hear others’ reviews and thoughts though. And I still love my compasses... very much doubt I’ll ever hit the trail without one.
