iOS has long been an attractive mobile platform for developers because of its lack of fragmentation. When a new major version of iOS is released, a flock of iPhone, iPad and iPod touch users are always quick to update; as a result, Chitika reports that the number of iOS devices running iOS 7 or later has already reached 74.1 percent in North America.
Google doesn’t enjoy the same luxury, as 24.1 percent of all Android devices continue to run the three-year-old Gingerbread version. According to the study, the remaining 25.9 percent of iPhones continue to run an outdated iOS version: iOS 6 (22.4%), iOS 5 (2.6%), iOS 4 (0.9%) and iOS 3 (0.1%). Comparatively, 63.8 percent of iPads have been updated to iOS 7 so far.
