This is a logo of a cloud made of three rounded circles. On top of the cloud is part of a gibbous moon. To the left of the moon are two cross shaped stars, one bigger than the other.
This is a Night 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.
