Google has introduced its Maps app for the iPhone, in the wake of complaints about Apple's software. Apple controversially replaced the search giant's mapping service with its own when it released its most recent handset, the iPhone 5. Google's app introduces functions previously restricted to Android devices. The firms are forced in part by a desire to gather data routinely generated by handsets using their respective software, as well as users' own feedback
Google offers a similar facility via Google Earth which is promoted in its main maps app, but involves switching into a part program. Between the facilities Google's iPhone app lacks that are present in its Android equivalent are indoor maps, the ability to download maps for offline viewing, and voice search. Google Maps, as much as any other map application, lives from the data that we get. However, for many users the key element will be the level of correctness that Google offers.
