Whatsapp for iOS 7 [redesign]

As of today Whatsapp still hasn't updated their app to the iOS7 style and as it's an app I use on a daily basis I decided to redesign it.

With this redesign I've tried to improve the UI as well as the UX because I find the original app not as efficient as I'd like it to be.

Make sure you checkout the attachment because it's fullsize and features 2 extra screens.

Thanks for taking the time to view this shot!
