Apple has updated the App Store Developer page, confirming that iOS 12 is now on 72% of all devices introduced in the last four years. The new statistic is a full 10% jump from the previous report back in November. The measurement for the update was all devices that came to the App Store on December 3, 2018.
The official figures from Apple are inline with what the research firm Mixpanel as reported. Last week, they showed iOS 12 on 75% of devices some ten weeks after the version launched.
