I’ve been hitting more puzzle caches and multi-caches lately. Without knowing how to add waypoints, I had only the Geocaching app’s home screen (which provides the current position’s coordinates) to go by.
I happened upon a few posts that described the waypoint flag button and was able to figure out this feature from there, but also thought it might be helpful for several others to see it in action. In the screen shots below you’ll see the process of creating a waypoint and changing the compass heading to point there.
I’m not completely certain, but it appears that the app retains this information even if you don’t “favorite” the geocache or save its maps.
