The icon is a picture of the logo for States. The icon is in the shape of 3 circles. All of the circles look to be the same exact size and shape;however, they are slightly overlapping eachother.
This is a States 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 13,300 icons, all in the same style and quality.
