74% of iPhones and 63% of iPads now run on iOS 7, Chitika reports

Apple sure has a handle on OS fragmentation. The company’s most recent release of their mobile OS, iOS 7 has already made its way to the majority of iPhones and iPads in North America. iOS 7 now functions on 74.1% of iPhones and 63.8% of iPads, accounting for 51% of North America’s iOS based internet traffic. This quick adoption blows the doors off of iOS 6 adoption, which had penetrated 83% of  iDevices six months following its release. It took only two months for iOS 7 to make it to 74%.

The data is via Chitika, who gathered the data by analyzing ad impressions gathered between October 25th and November 18th in Canada and the U.S.
Around 22.4% of iPhones are still operating on iOS 6, while 24.6% of iPads operate on the old iOS. Surprisingly, iOS 5 is still being used on many iPads, as the data shows an 8.8% iOS 5 usage rate in its iPad traffic. The spike in iOS adoption could have a correlation to brisk iPhone 5S sales, which has resulted in Apple increasing production of said smartphones.
