After three-and-a-half months on the market, iOS 7 is installed on some 78 percent of devices connecting to the App Store, according to the latest numbers posted on Apple’s App Store support page for developers.

The company puts iOS 6 adoption at 18 percent, and older OS versions at 4 percent. The data from Apple is likely the most accurate adoption data we will see and is the most relevant for developers as its taken directly from the App Store.

Earlier in December, Apple reported iOS 7 adoption at 74 percent.

I’d like to see numbers on how many people regretted it after updating. :D

Will never understand why Apple sees ‘fragmentation’ as an issue. It hardly matters.

Ha! You obviously aren’t a developer.

It would be interesting to see what percentage of devices that can’t run iOS 7 are in these percentages to get a good idea of how many devices can upgrade but haven’t.
Not bad for something that’s been out for less than half a year.

Android 4 has been out for over 2 years and there are still fewer devices percentage wise running version 4 or higher.

How many of those adoption number will change if they allow iOS6 downgrade?
