 <p>Apple's MapKit only used Google Maps up to iOS 5.1 as stated in the <a href="https://developer.apple.com/library/ios/documentation/MapKit/Reference/MKMapView_Class/MKMapView/MKMapView.html" rel="nofollow">"Important" note in the <code>MKMapView</code> class reference</a>:</p> <blockquote> <p><strong>Important</strong>: In iOS 5.1 and earlier, the Map Kit framework uses the Google Mobile Maps (GMM) service to provide map data.</p> </blockquote> <p>Since then, and including iOS 7.1, MapKit uses Apple's mapping service instead. </p> <p>However, regardless of iOS version, the developer is not charged for using maps.</p>
