Is there a way on any IOS map app (Apple Maps, Google Maps, MapQuest) to save a waypoint? For instance, I go to my friend's new house and want to save that location for future reference. On my Garmin, of course this is a snap. But, if I could do that on any IOS map app, I would really have no need for the Garmin! Does anyone know of a way to do this on an IOS map app?
