Idea of Popular Filled Icon
It's a logo to represent something is a popular topic. The logo is a talk bubble with a 5 pointed star in the middle. The talk bubble its self is a circle with a pointed tail at the bottom left side of the bubble.
This is a Popular 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.
