Anything that keeps maps in local storage so you can use GPS while offline is somewhere between very helpful and lifesaving. Sounds like Osmand is in there.

Organic Maps lets you download also. I got it specifically for backpacking because it enabled that. It certainly has been worth the $0. I should probably donate something each trip.

Definetly one of the subscriptions I don't regret as much as others but still a steep cost for my frequency of usage. I need it approx 6 weeks per year and only as backup when traveling/hiking.

A free alternative (simply Osm) is much appreciated.
