Used when I'm in the field alone. I mostly have service at this site, so losing tracking offline isn't a problem for long. I haven't figured out how to select my actual work location as the destination, so I use a nearby town. All in all, it's unclear to me whether offline and custom destinations are options, but I haven't watched tutorials.

The Best Outdoor app I have found. Downloaded as a budget alternative to Inreach as most of the places I go have some cell signal and needed something for family to track my trip. Saves me hunderds of dollars. The awsome design, offline maps that show cell signal spots, and trail stats are a bonus. I highly recommend this app to any outdoor folks.

From other hiking maps I am used to get a list of trails with rating of difficulty when searching an area for some hikes. With this app there is no such feature available, at least I couldn't find it. I think this app could be useful and great if you already know the trails and name if the trails you want to hike. Other than that useless app.
