Apple published an updated chart on its developer Web site for the iOS App Store, which shows that iOS 7 is now on 74 percent of all iOS devices. This means adoption of the operating system has grown 10 percent since numbers last reported in October.
The tech giant debuted iOS 7 in September, along with the launch of its new iPhone 5S and 5C. Just one month later, Apple released its new iPad Air. All of these latest products are shipped with iOS 7.
According to Apple's chart, 22 percent of devices are still running iOS 6 and 4 percent are using an even earlier operating system. Like previous releases, iOS 7 is not available on some older devices, which include iPhones prior to the iPhone 4, iPods before the fifth-generation iPod Touch, or the original iPad.
Looking forward, Apple is expected to release iOS 7.1 in the near future. The company released the software in beta to registered developers last month.
