Idea of Double Tap Icon
It is a circle with two waves stacked above it. The waves are curves, almost like partial circles. If it could be likened to anything, it looks sort of like the Wi-Fi symbol.
This is a Double Tap 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.
