Idea of Synchronize Filled Icon
There are 2 circular lines following each other with an arrow on the ends of the circular lines. The are working together as a revolving circle to complete a rotation.
This is a Synchronize Filled 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 13,900 icons, all in the same style and quality.
