Over 100 million iOS users have adopted Apple's latest mobile OS.
Updated metrics based on advert impressions from when iOS 6 launched last month found that 60 percent of iPhone users are already on iOS 6, while the figure is 45 percent for iPad users, and 39 percent for iPod owners.
"Overall, this data points to Apple doing an outstanding job of keeping their user base up-to-date with the latest OS," Chitika said. "By comparison, Google's latest data shows only 22 percent of its users being on its two most recent versions of Android."
24 hours after iOS 6 launched, Chitika said a total of 15 percent of iOS users installed the latest operating system. The figure was followed by official numbers provided by Apple when the firm announced that, along with iPhone 5's opening weekend sales, over 100 million iDevice users had adopted to iOS 6.
iOS 6, which was released on September 19, adds over 200 new features, according to Apple. Particularly, it replaces Google Maps with Apple's own maps app, which has been so heavily scrutinized that Apple CEO Tim Cook issued an apology pertaining to the app's flaws.
