Apple has released iOS 7 adoption statistic on its developer website, unusually nestling the information within an App Store Distribution section of the site. The company claims that “74% of devices are using iOS 7,” though it’s interesting how Apple reached that number.
It says that the 74% was “as measured by the App Store during a 7‑day period ending December 1, 2013,” which would rule out iOS users who didn’t visit the App Store in that given week, a different and less absolute metric than has been offered by the company in the past. By contrast, Apple suggests that 22 percent of devices are using iOS 6, with 4 percent of devices still using an older edition of iOS.
