This is a Timer 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 12,800 icons, all in the same style and quality.
The timer icon can be used in a variety of ways. It can be used in articles and tutorials about cooking, studying, or any other activity that requires time limitations. There are a variety of icons to choose from.
Timers are often used in study regiments, so this icon would be great in an article that explains effective study habits.
Timers are often used in the process of cooking, so it would be a useful icon to use for recipe websites.
It would also be a great icon to use with in articles about exercise, which often has a time limit.
