Bio_Logik When I last used OsmAnd I found the quality of the address search results were not good enough for my needs. So I switched to Organic Maps for offline map navigation, and am happy enough with that. Like OsmAnd and Maps.me, the map data comes from openstreetmap.org
I have commonly seen Magic Earth also recommended.
For public transport navigation, I usually use the PWA for Google Maps in Vanadium or the website of the operator (e.g. TfL in London).
