Idea of Ratings Filled Icon
It's a logo representing an upwards rating trend. There are two "pages", stacked one above the other, with the bottom sheet stacked slightly to the right and under the top sheet, with a an arrow pointing up and to the right, with a small downward trend in the middle of the top sheet.
This is a Ratings 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.
