The Icons & Coffee group, makers of the popular ‘Perspective’ icon set for OmniFocus, have released another awesome set of icons: ‘Essence’ for iOS 7. With 300 icons covering a wide variety of categories, this set is the perfect tool for developers who want their apps to look great on iOS 7.

When you buy the set, you get a .zip archive that contains transparent PNGs in two resolutions (25×25 and 50×50) and two colors (white and dark gray). It’s all sorted into folders for your convenience, and every PNG file is Xcode 5-ready. There’s also an .ai file containing all the icons in vector format for you to play with.

For a limited time, the Essence icon set is only $20. It will eventually go up to $30 though, so strike while the iron’s hot, I’d say.
