Nokia says it has started providing mapping services for free download in Apple's App Store, after a successful launch of the service on Android devices.
The HERE offline maps, with navigation and search features covering more than 150 countries, is immediately available for devices using the iOS operating system, such as iPhones and iPads.
Nokia said Thursday that more than 4 million users have downloaded HERE apps since its Android launch last year.
The maps, a fixed feature on Windows phones, contain real-time traffic information for more than 40 countries.
Nokia's HERE is one of the few global computerized roadmap providers, with a long history of working with automotive companies and an 80 percent market share for embedded automotive maps.
