Update 1/20: App Store Distribution Data updated today revealing iOS 8 adoption has climbed 1% from its previous measure at 68%. iOS 8 adoption now measures at 69% of active devices according to App Store data captured January 19th. The rate increase is in line with MixPanel’s increase to roughly 71% now up from roughly 70% toward the start of the month.

Apple has shared its latest App Store Distribution Data on iOS 8 adoption to report that some version of its current mobile operating system is installed on 68% of iPhones, iPads, and iPod touches. Apple tracks the rate of iOS 8 adoption based on devices accessing the App Store with the current data being captured on January 5th, 2015.

The new iOS 8 adoption percentage jumps 8 points since late November when Apple reported that 60% of devices were using iOS 8 with incremental jumps between then and now.

For comparison, analytics company Mixpanel reports iOS 8 adoption just above Apple’s own data at roughly 70% in its latest numbers.

How does 68-70% adoption of iOS 8 compare to adoption of Apple’s previous major update with iOS 7? According to Mixpanel’s analytics, users running iOS 7 during the same period a year ago reached just over 83%, putting iOS 7 adoption some 13 points higher than that of iOS 8 currently and continuing a trend we’ve previously seen.
