Such subtle yet noticeable details lead to the overall de-cluttering of user interface, leading to more space freed up for icons. We’ve complied the top fifteen examples of the cleanest, concise, and most modern looking icons to showcase the newest design trends that build the new iOS visual experience.
I disagree with a few of these, but it’s a pretty good list. It’s amazing to me to see that even the icons we considered “trendy” and “flat” before the announcement of iOS 7 are starting to look a little dated and chunky. The shadows on the bottom of icons such as Snapseed don’t fit with iOS 7 at all.
