When Apple maps on iOS originally came out, it was somewhat of a laughing stock among tech geeks around the world. It had a lot of bugs and errors, and seemed to be a failed attempt at launching something that could be as good as Google Maps. Despite this, Google Maps has lost a whopping 23 million users to iOS since Apple Maps was first released, almost a quarter of the 81 million user that it used to have.
A year after Apple maps was originally launched, it now has a total of 35 million users. It is important to note that Google still has more users with a total of 58.7 million users across both Android and Google Maps for iOS. Around 6 million of those users are using it from the Google Maps app for iOS.
Maps data is extremely important for both Apple and Google. It helps both companies monitor information like traffic jams, and it also helps Google provide location based advertising, which is an extremely important source of income for Google.
