This image is composed of a circle in the center. Around that circle are three concentric rings of increasing diameter. Going from the center circle is a diagonal arrow shape without the arrowhead going towards the upper right.
This is a Goal 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.
