I have CoMaps and OsmAnd~ installed. The "~" is important, it's the the f-droid version that has most of the paid features for free.

The one I use most though is c:geo, it's actually designed for a game called geocaching, but its offline maps are simple and work really well.

For the few times I used it off roads OsmAND has been great

Definitely OsmAnd for me

I used CoMaps very well when i hiked in Spain and parts of Scandinavia, I am surprised how well hiking oaths or just paths in general are marked. it has a nice mix of what an good app should be and the feeling of having a paper map.

I'm a noob, so there's that, but I use Organic Maps, which is basic and does offline driving, too.

I've never seen the point of all these apps; the only 3 i think are worth caring about is comaps, osmand (both of these basically do the same thing), and especially trailsense if you don't mind something which is more of a toolbox than a navigation app.

But really the important thing is having a phone with as good GPS hardware as possible, ideally you'd bring a proper separate GPS reciever that can plug into the phone. Modern GPS can be so good that you'll get at least a rough position even in forests, and when you have your position everything else becomes relatively trivial.

I follow the color signs on the tree trunks... Yeah I dont go hiking much lol

Most of my outdoor stuff is in Australia. I found an app years ago called "Australia Topo Maps" which had a one time payment for the ability to use offline maps.

I've tried many others, and keep coming back to this one.

Despite the name, I can cache any OSM topo map anywhere in the world. They also have a suite of country-specific apps, which likely just have different options for map sources.

Locus Map

OruxMaps is the best I've ever found (and it's free). Been using it for nearly 15 years, still getting updated. Extremely flexible and powerful, though navigating the app itself sometimes feels kind of obtuse.

OpenAndroMaps for getting nice maps to use with it.
