I use a map app for the first time, because I don’t want to make a mistake on a route. After that, I rely upon myself.
I use a map app in a similar manner. I use it to look up the route(s), identify key points with landmarks, memorize said key points and go. By my third trip it is in my head.
I prefer paper maps which I believe are extinct and refuse to use GPS. I do copy of maps from Mapquest and use them that way. My wife loves her GPS but I get where I need o go more reliably.
