One of the more obvious alterations to Apple's iOS 7 is the overall change in design ethos, with Jony Ive leading the Cupertino company towards a flatter, skeuo-free environment. It's fair to say that John Gruber's pre-WWDC assessment of the interface, in that it would be polarizing, has rung true, but irrespective of consensus, it is the look Apple will be sticking with. While Android won't be seeing such radical changes any time soon - at least, not from what we hear - those running Google's mobile OS can get a little taster of Apple's new UI through an app called iOS 7 Calci, which offers a passable emulation of Apple's new Calculator app.
