Was iOS 7 created in Microsoft Word?

Apple Says;

"Nothing we’ve ever created has been designed just to look beautiful. That’s approaching the opportunity from the wrong end. Instead, as we reconsidered iOS, our purpose was to create an experience that was simpler, more useful, and more enjoyable — while building on the things people love about iOS. Ultimately, redesigning the way it works led us to redesign the way it looks. Because good design is design that’s in service of the experience."
