Apple has the highly-anticipated adoption statistics for iOS 26 for the first time. The company says that 74% of all devices introduced in the last four years are running iOS 26, while 66% of all devices are running iOS 26.

These numbers are based on the devices that transacted on the App Store on February 12, 2026. They were published on Apple’s developer website today.

• Earlier: 6%

Of all devices

• iPadOS 26: 57%
• iPadOS 18: 26%

There’s a ton of nuance to these numbers that’s important to keep in mind. First, iOS 26 dropped three iPhone models this year. The update is not available on the iPhone XS, iPhone XS Max, and iPhone XR. iOS 18, meanwhile, was supported on all the same iPhone models as iOS 17. This plays a factor in update rates.

Based on these number, it’s clear that iPhone users are installing iOS 26 at a slightly slower pace than iOS 18.

It’s also clear, however, that iOS 26 hasn’t been a disaster like some pundits would want you to believe. For a software update as big as iOS 26, these numbers are quite respectable.
