An alernative to Magic Earth would be Organic Maps. https://organicmaps.app/
Though it's not as focused on driving, it seems. But may be good enough.

I haven't tried it much in the US.
The US should be pretty good for trails, reasonable for streets and highly variable for addresses and POIs.
One advantage of Organic Maps is that it integrates well with OpenStreetMap. As I live in a place where OSM coverage is pretty average, I have fun adding places I know through this application and make small contributions in my own way. It also does not collect any user data. Give it a try.
I have the luxury to live in central Europe, and here both are much, much closer in amount of detail.
