Apple's iOS 7, released on September 18, 2013, has rocketed to over 70 percent adoption on iPhones in North America and is poised to greatly outpace iOS 6 in its first six months. The iPad is not far behind.
The adoption of iOS 7 has been meteoric, according to a Chitika research report, recently released, which collated data from tens of millions of U.S. and Canadian iOS-based ad impressions from roughly November 2012 to November 2013. Because the sample size is so large, it is very likely of statistical significance.

In more detail, iOS 7 now has a 74.1 percent presence on iPhones and 63.8 percent presence on iPads. About a quarter of both platforms are still running iOS 6.

The latest analysis again underscores that iPhone users, and iPad users to a lesser extent, update at extremely high rates, acting as a distinctive selling point when it comes to attracting application and mobile Web developers to the platform.
