The image is a rectangle with an arrow coming from the top of it. The arrow is centered and pointing down. Directing underneath the rectangle is the word trial in all capital letters.
This is a Trial 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 13,100 icons, all in the same style and quality.
