If you are trying to minimize google maps use Organic Maps is the way to go imo. Fast loading, simple slick interface with minimal fuss. It’s a beautiful thing!
OSMand is not nearly as slick and polished and is kind of clunky by comparison. That is because it isn’t trying to be like Google maps at all. It runs fine straight from the app store but the real beauty of it is the tinkering it allows. You can make multiple map presets fine tuned the way you like it. It’s the midpoint between Organic Maps and ATAK
For the unfamiliar that’s another cool thing about using OSM data. If some of your favorite places are missing from the map you can just add it!
There’s several ways to do it but if you have a laptop the easiest way is to use the editor on openstreetmap.org. They have a quick and easy interactive tutorial to show you the ropes and then you are free to add what you feel is important!
