While Apple (NASDAQ:AAPL) fans and developers eagerly wait to see what changes the Cupertino-based company implemented in the soon-to-be-unveiled iOS 8, the adoption rate for Apple’s last mobile operating system continues to climb. A recently released study from online ad network company Chitika showed that Apple’s iOS 7 continues to be adopted by users at a rapid pace. According to data gleaned from the tens of millions of online ad impressions generated in Chitika’s North American network, 89.7 percent of U.S. and Canadian iPhone Web traffic is produced by devices running some version of iOS 7.
The second most popular iOS version was iOS 6 with an 8.8 percent share, followed by iOS 5 with a 1.0 percent share. Meanwhile, iOS 4 or earlier only had a 0.5 percent share. As noted by Chitika, iOS 7’s iPhone share has jumped by 5.4 percentage points since a previous study in February. Apple users have historically shown a tendency to quickly adopt the latest mobile operating system. Five days after iOS 7 was released last September, Apple noted that “more than 200 million iOS devices are now running the completely redesigned iOS 7, making it the fastest software upgrade in history.”
Although almost 90 percent of iPhone users in the U.S. and Canada are now running the latest iOS, it should be noted that this is a slightly lower rate of adoption than what was recorded for iOS 6 during the same time period last year. Before last year’s WWDC, 92.7 percent of iPhones in North America were found to be running iOS 6. However, unlike iOS 6, iOS 7 featured a completely redesigned user interface with a new, flatter appearance. It’s quite likely that the radical changes found in iOS 7 made some users hesitant to upgrade. This reluctance to upgrade may have also been exacerbated by reports that the new zooming effects and parallax animations found in iOS 7 were making some early adopters nauseous. However, Apple later implemented setting changes that allowed users to disable many of these problematic effects.
