After five and a half weeks of availability, Apple’s iOS 8 operating system is now installed on 52 percent of iOS devices, according to new numbers posted on Apple’s App Store support page for developers.

The number is measured by Apple through App Store stats.

iOS 8 has been, in my personal experience, “difficult” to explain: some of its new features like widgets and extensions are best demonstrated with third-party apps that not everybody has, and additions like Handoff and keyboards aren’t immediately noticeable like a new design. It appears that more people are now upgrading to a new major version of iOS after a few updates, but there are also new iPhones and iPads with iOS 8.1 pre-installed that may have influenced Apple’s statistics.

Still, iOS 8 numbers are going up and that should be good news for app developers, but it doesn’t seem like iOS 7 can be completely left behind yet.
