After being stuck at the 77 percent mark for a full four weeks, Apple on Monday updated its App Store dashboard for developers with the latest stats on iOS 9 adoption. As per the newest device logs captured on March 7, 2016, iOS 9 is installed on 79 percent of devices that recently accessed the App Store.
The two-point increase versus the 77 percent adoption rate recorded a month ago came at the expense of iOS 8 and earlier versions that have lost ground to iOS 9.
