Great question! I had never thought of whether a smartphone points to grid or magenetic north. Quick google search shows that you can set at iPhone to either[1]. As for specialized maps for orienteering: Orienteering maps are different than normal street maps. They always have gridlines, very precise scales and clear markings of major and minor terrain features[2]. Then, on top of the data presented on a map you have maps of different scales. For example, one inch of a 1:24,000(pronounced - one over twenty four thousand) map represents 24,000 inches on the ground. A 1:250,000 map it very zoomed out relative to a 1:10,000 map. If you're hiking 500 miles of the PCT you may want a 1:100,000 or 1:250,000 scale map because you don't need to know every twist and turn because you're following a trail. But if I dropped you off in the middle of nowhere and said walk due west to a specific point 10 kilometers due westyou'd want a map that's 1:10,000-1:24,000 scale because you need to see specific terrain features. To answer your question more directly: There are what you would "orienteering-specific" maps because they represent some critical data well. For orienteering you use the one that works for you based on what information you need to get you from point A-B [1] - https://www.idownloadblog.com/2017/04/28/how-to-iphone-compass-apple-maps-navigation/ https://www.idownloadblog.com/2017/04/28/how-to-iphone-compa...
