The icon is shaped like a rectangle standing upright. The top right end of the rectangle is slightly folded inward. A little lower than the center of the icon are the capital letters AAC.
This is a AAC icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,700 icons, all in the same style and quality.
