Is that a webview loading Gmaps? That's not what I expected to call "degoogling", haha.
The OSMand UX is clearly not made for casual use, but Comaps is basically the main user-friendly application. It is missing a couple of commonly-used features though, most notably traffic information, which of course Google bases on data collected from its users.
I have used OsmAnd for maybe 10y. And it has been surprisingly good
Several countries. Works offline. Saves the journey taken
Not the best at finding places sometimes. Food places and ratings still has to be google or trip avisor, but those are very relative too. Wherever you go the key e some preparation anyway
