I use Magic Earth, it has the best UI IMO.

OsmAnd+ the best

That’s what I use. Some may get too overwhelmed with the feature set it has, so Organic Maps would be a more basic nav app.

But… OsmAnd+ is far more advanced than Google Maps, and can be customized every which way.

Another bonus: You’ll never see ads masquerading as POIs on a map.😀

MagicEarth is decent, I’ve not had any luck with osmand or organic maps.
