Apple announced on Thursday that it had completed deployment of its new and improved maps software in the United States.

Users of the Maps app, which comes preinstalled on iPhones, now see more detailed roads, buildings, parks and other landmarks when looking at maps in the United States. Navigation is also more accurate, Apple said.

Other new features that the more detailed maps enable include a "look around" mode, which appears as a binoculars icon on the upper right-hand corner of the app. It enables users to explore and look around 360-degree streetscapes, similar to Google Maps' Street View, in places including New York City, the San Francisco Bay Area and Los Angeles.

Apple said it also added real-time transit schedules, so that in certain cities, users can see exactly when a train or bus is arriving or its exact location.

Apple first announced that it planned to drastically improve its maps in 2018 using a process that involved fleets of Apple Maps vans equipped with cameras and sensors to collect images and distance, as well as anonymized data from iPhones.

"With Maps, no sign-in is required and it is not connected to an Apple ID in any way," Apple said in a privacy notice.
