An Apple fan, Mohamed Kerroudj has posted a couple of concept videos on where Apple could take its UI in iOS 7. Looking reminiscent of the flat Windows Phone design language combined with elements of Google Now and the new popular new Mailbox app for iOS, Kerroudj's approach has a minimalist style. Kerroudj's version of iOS 7 would have a much more functional lock-screen, while also removing the skeumorphism apparent in native iOS apps like Calendar.
