Apple introduced its latest mobile operating system at its keynote for the 2013 Worldwide Developers Conference on Monday, but even though rumors predicted iOS 7 would be a big visual change, nobody outside of Cupertino, Calif., was prepared for the massive makeover given to iOS 7 in both visuals and functional features. During the unveiling, the WWDC crowd cheered at various moments, and even offered a standing ovation at the end of the introductory video.

“True simplicity is derived from so much more than just the absence of clutter and ornamentation. It’s about bringing order to complexity,” Apple lead designer Jony Ive said in the iOS 7 video. “iOS 7 is a clear representation of these goals. It has a new structure that’s coherent and applied across the entire system. We’ve considered the tiniest details, like refining the typography, like much larger ones to redefining all new icons, and creating a grid system to create a much more harmonious relationship between individual apps. We’ve also included a whole new palette of colors. Distinct, functional layers help create hierarchy and order, and the user of translucency gives you a sense of your context. These planes combined with new approaches to animation and motion, create a sense of depth and vitality.”

While we’ve explained how some of the new features work, it’s best to see iOS 7 in action. Check out these iOS 7 screenshots, which show off many of the system’s new-look features and applications, and let us know what you think in the comments section at the bottom of the page.
