Idea of Gender Filled Icon
It's a gender icon, represented by two circles, interlocking. The one to the left is lower, with a cross, "addition sign" extending diagonally to the left downward. The circle that is higher and to the right has an arrow pointing upwards and to the right extending from its outer center. These represent male and female.
This is a Gender Filled 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 13,900 icons, all in the same style and quality.
