Though it was only released yesterday morning, iOS 7.1 has already been installed on 5.9 percent of iOS devices in North America, according to a new report from analytics firm Chitika. To get its numbers, Chitika measured ad impressions from tens of millions of iOS-based devices in the U.S. and Canada from March 9 to March 11, 2014. The adoption rates are similar to those of iOS 7.0.6, which offered a critical security fix and was installed on 13.3 percent of iOS devices 48 hours after release and 25 percent of devices after four days. As with most minor version updates, iOS 7.1 adoption rates have been less dramatic than those of its major-version counterparts.
