The icon shows two heart shapes. One is larger standing upright behind a second one that is tilted down and smaller in size. The hearts would represent a lowing emotion towards something.
This is a Romance 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.
