Waypoints can save and display on the map as you navigate.

If enabled, waypoints are saved to iCloud and can be accessed from all your devices. Allowing you to do things like save on your iPhone and then edit on your iPad later.

All of your waypoints can be exported to a kml file allowing you to display them on applications like Google Earth.
