Previous release, iOS 6, now down to 12 percent
As of March 23, Apple says 85 percent of active users of iOS devices (iPad, iPhone, iPod touch) are running some version of iOS 7. This follows figures that showed a majority of users -- 52 percent -- had adopted iOS 7 just a week after its release last September. By Christmas, it was on 78 percent of compatible devices. Some 12 percent of users are on iOS 6, with the remaining three percent running older devices limited to older releases. The rapid adoption rate of iOS releases continues to be a major security and developer advantage over Android.
By comparison, users of KitKat (the most recent major Android OS, v4.4) have yet to crack 10 percent of its active user base, owing to the platform's fragmentation. The remarkable takeup rate of iOS 7 is driven in part by a refreshed look, which has been polished further in the latest release, v7.1.
Another factor may have been security concerns that prompted Apple to issue the iOS 7.0.6 update just a week ahead of iOS 7.1's arrival. Both updates patched a significant SSL/VPN security flaw that could have allowed for a "man in the middle" wireless communication decryption attack. The 7.1 update also featured a fix for a Touch ID issue, CarPlay support for future car models, improvements in enterprise features and general fixes and tweaks.
