hcs_$reboot writes "After the disastrous Apple Maps replacement over Google Maps in September, Google has a Maps app on iOS approved and released by Apple today. The app includes turn-by-turn directions, vector-based graphics and live traffic data. It's available from the Apple Store for iPhone and iPod touch (and iPad — iPhone format)."
Adds reader snowtigger: "It's a sharper looking, vector-based map that loads quickly and provides smooth tilting and rotating of 2D and 3D views. Google also released the Google Maps SDK for iOS, and a simple URL scheme to help developers use Google Maps when building their beautiful and innovative apps. The new Google Maps app is available for the iPhone and iPod Touch (4th gen) iOS 5.1 and higher, in more than 40 countries and 29 languages."
SlashCloud points out that Apple's own maps will be forced to improve as a consequence
: "Directions will become more accurate, major towns and landmarks will appear in their proper places. But now that a free, standalone Google Maps app is available for download from Apple’s App Store, will iOS users even give those improving Apple Maps a chance?"
