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 Double Tap icon has Android KitKat style
. If you use the icons for Android apps, we recommend using our latest Material Icons icon pack (please check our sidebar on the right). Otherwise, it's a solid icon pack that looks good in small resolutions, either on the web or in print. It's characterized by thick lines, smooth corners, and is optimized for 24x24 pixels.
