One of the domain where iOS really shines is animations. Developers are pushing the limits to find new and innovative animations in iOS apps and Beautiful Pixels has selected some of them in Best of 2012: UI Animations:. From Google+ apps to National Parks, each of these apps uses cool animations that add to the app value. Twitterrific 5’s pull-to-refresh animation, while not technically impressive, is really cute.
Core Animation, the iOS framework for UI animations, is really powerful, you can even do 3D animations and particles effect (starting from iOS 5) - see the demos in the WWDC 2011 Core Animation Essentials session. There are other good WWDC videos on Core Animations:
