To make the transition process we stumbled upon a neat package of 300 icons drawn in the iOS 7 aesthetics and sold for developers who lack the designers or the skills to create their own icons. The 300-icon pack consists of drawings in two colors for everything you could imagine. It looks great and would easily integrate with the new iOS 7 looks.
The icon pack is called Essence and is currently sold for $19.99. It seems like something iOS developers would enjoy, so if you are one of them you might like what you see in the source link right below.
