This is a Finger Up 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 12,400 icons, all in the same style and quality.
We've received the idea on February 25, 2012 and created the icons on April 10, 2012
Touch-related icons demonstrating things like pinch-to-zoom, multi-touch, etc.
