Firefox? That’s a strange way to spell LibreWolf.

One thing I like about Osmand for driving is that it tells you which lane(s) you should to be in for the next turn/junction/roundabout. It’s especially useful for large junctions and/or in busy traffic. I’ve had it do the “detour route” that you talk about, but it’s never been anything major like a complete square that’s lead to wasting time.

OSMAnd is very good, with a lot of features, but lately I have been using Organic Maps. It has fewer features but is SO MUCH FASTER when rendering maps.
