iOS 7’s adoption rate has increased 10 percentage points since October, a remarkable growth considering a radical overhaul of the platform. Apple

In an update to its developer website on Thursday, Apple (NASDAQ:AAPL) posted a chart showing the distribution of devices on various versions of iOS, and it was the latest edition of the mobile-operating system -- iOS 7 -- that led the pack with a huge margin.

According to Apple, ever since its availability in the market, the redesigned iOS 7 has been installed on a staggering 74 percent of devices as of Dec. 1. The adoption of the last-generation version of the platform, iOS 6, was put at 22 percent, while the remaining 4 percent was attributed to older versions of the software.

As noted by TechCrunch, the iOS 7’s adoption rate has grown by 10 percent since October, which is seen as a remarkable increase considering the radical overhaul of the platform in the update. The growth rate is also astonishing given the fact that the iOS 7 has been on the market for less than three months.

The company released the new software on Sept. 18, alongside the unveiling of the iPhone 5s and iPhone 5c.
