19. Maps Adds One Finger Zoom, Lanes, Flyover
This won’t be anything new to Google Maps users, but the built-in Maps app from Apple now supports lane directions, interior building directions in some cases (great for airports), and single-finger zoom.
Rather than just pinch with two fingers, you can double tap to zoom, or double tap but on the second one, hold your finger on the screen, then move it around to get the same effect you have with pinching.
Perhaps the nicest update to Maps is the improved 3D Flyover view for select locations. If you pick a destination and it says Flyover Tour, give it a whirl.
