Here's a new icon set and the black version of my White Line Round icons. There are 100 icons in all and cover various Android and system apps.
This icon set has been updated as of 2-29. Leap day.
Disclaimer: These icons look best and are most visible with a light colored theme.
(Here's the Photoshop template so that you can make your own icons for whatever app you want. All I ask is for you to give me credit for the original design. Thanks!)
