The icon shows two horizontal numbers. The number at the top is a 1 and the number at the bottom is a 2. At the right of the numbers is an arrow that is pointing downwards.
This is a Numeric 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.
