This App Symbol icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,900 icons, all in the same style and quality.
The icon is a copy of the logo used by the App Store present on all iOS devices and run by Apple, Inc. The logo is enclosed within a rounded square on the outside, and a circle inside of the square. The icon represents the presence of an application.
