Google has released a native version of its Maps app for the iPhone. It follows Apple’s switch to its own map software which stopped Google powering the handset’s default app. The move was widely criticised after numerous mistakes were found in Apple Maps’s search results. Google’s new iPhone app introduces some functionality previously restricted to Android devices. One analyst said it would prove popular, but added that Nokia still posed a challenge. The Finnish company recently launched its own free maps app for the iPhone. The firms are motivated in part by a desire to gather data automatically generated by handsets using their respective software, as well as users’ own feedback. This allows them to fine-tune their services and improve the accuracy of features such as traffic status updates.
