Apple shared updated adoption numbers for iOS 26 and iPadOS 26, revealing how many iPhones and iPads were running those software versions the day before WWDC 2026 began and the first iOS 27 developer beta was released.
These adoption figures are based on iPhones and iPads transacted in the App Store on Sunday, June 7, according to Apple.
The statistics are as follows:

- 79% of all iPhones were running iOS 26.
- 79% of all iPads released in the last four years used iPadOS 26.
