The icon for "wakeup hill on stairs" shows the outline of a man walking up stars. The stairs are shown as zig-zag lines, running from the bottom left of the image upwards to the top right. The man appears to be in motion.
This is a Staircase 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.
