With the release of iOS 7, a lot of concepts are coming up for icons and design suggestions. Apple’s iOS 7 beta was the first update since the main release and it was focussed on performance tweaks and some minimal design changes.
There’s major interface change from iOS 6 to iOS 7, and because of this, the app developers should also adopt the Flat UI or at least a matching interface so as to give users a similar feel while browsing through apps.
A designer over at dribbble published some iOS 7 app redesign suggestions which are pretty well designed. The concepts also adopts flat user interface and looks better than previous skeuomorphic design.
