The new Mr. Reader icon

The goal was to carry the spirit of Mr. Reader to the new OS. So the icon needed to feel lighter and right at home on iOS 7. I won’t lie, the design process itself for a typical icon of the new platform which iOS 7 is, allows for a much more simpler approach than in the pre-iOS 7 era. With iOS 7 icons you spend more time thinking about what works best with Apple’s paradigm of minimalism, rather than fine-tuning every pixel of a drop-shadow.
