Google Maps features driving, walking, and transit directions for both the iPhone and iPad, complete with voice guided GPS navigation. Google Maps is currently available in over 220 countries and territories with transit directions included for over 15,000 major cities around the world. Google Maps also comes with Google's popular Street View feature built right in to help you find exactly what you're looking for.
When the iPhone originally debuted in 2007, a version of Google Maps came pre-installed on every iPhone. When iOS 6 was released in the fall of 2012, Google Maps was removed as a default app and replaced with Apple's own mapping solution, Apple Maps. However, Google quickly released Google Maps as a standalone app through the iOS App Store. This is the version of Google Maps that is currently still available and regularly updated.
Google Maps is debatably one of the best free direction and transit solutions available today. Since Apple Maps doesn't currently support transit directions, anyone who uses public transportation will find Google Maps to better suit their needs. Other features of Google Maps for iPhone and iPad include detailed information from Google Places on over 100 million locations worldwide. You can also see any reviews available on Google for restaurants and other attractions such as hotels via Google Maps. When you're behind the wheel, Google Maps features live traffic information as well as accident reports so you can plan your route and change plans according to current conditions.
Since Google Maps pulls location information from Google's massive database of locations, many points of interest such as museums, public buildings, and restaurants also show interior photos and comments from other Google users, which makes Google Maps a very handy companion when traveling in areas you aren't familiar with.
