From 9to5Mac’s report:
The new interface is said to be “very, very flat,” according to one source. Another person said that the interface loses all signs of gloss, shine, and skeumorphism seen across current and past versions of iOS. Another source framed the new OS as having a level of “flatness” approaching recent releases of Microsoft’s Windows Phone “Metro” UI.
iOS 7 is codenamed “Innsbruck,” and among other changes, includes an all-new icon set for Apple’s stock iOS apps, newly designed toolbars, tab bars and other iOS UI elements. Game Center’s green-felt design would be thrown out in favor of a more “colorful” look, similar to the WWDC logo.
Another exciting thing Apple’s reportedly working on is the addition of easily ‘glance-able’ information, an area where Android currently excels with tools like Google Now and other third-party widgets. A prototype version let users access “panels” by swiping from either edge of the device, though what information these panels would display isn’t known.
Here are a few screenshots showing some well-known “flat” UIs, giving you an idea of what iOS 7 might look like:
These changes to iOS 7 sound very exciting, but we also hope that Apple’s changing the functional aspect of the OS as well, allowing apps to communicate with each other, making notifications better and of course improving iCloud.
