OsmAnd is a great powerusers app. I use it daily.

However, I would not recommend OsmAnd to a normie. My family members, especially the older ones, all use CoMaps because it is much more friendly to them.

100% this. I use OsmAnd very very frequently (it displays on my dash via Android Auto whenever I drive), but try and do something like load a GPX and show the line in a given color... Or add a pin at a specific point... It's not straightforward at all.

Powerful, but very not straightforward.
