The Wall Street Journal is reporting that Google is working to submit a standalone Maps app for iOS. Of course, Google is doing this due to Apple's switch away from Google's data when the company made the switch to an in-house solution when iOS 6 was released.
This new app will feature turn-by-turn navigation, which has been offered on the Android Google Maps app for some time. This will directly compete with Apple's own Maps application. The same application that has come under fire since its introduction due to its relatively poor database of locations and information.
The report also notes that Eddy Cue, Apple's SVP of Services, has taken more control over improving Maps. Maps and Siri both came under Cue's control when Scott Forstall, who was in charge of iOS, left the company last month, and his responsibilities were divvied up amongst the other executives.
