You can find pins, places, guides, and routes in one place: your library in the Maps app. Add your own personal notes—visible only to you—to saved places, or pin your most frequently visited places for easier access.
Go to the Maps app , then tap Add to Library.
You can read the notes you add to a place at any time, but they aren’t visible to others if you share the place.
Go to the Maps app on your iPhone.
Below Library, tap , then tap Places.
