The pack includes four app icons designed for writing and to-do apps. All icons have been re-sized to 512px, 114px, 72px and 57px. The PSD files are all layered and completely customizable. You can use the custom patterns already included in the files or you can choose your own patterns. Any other attribute – such as color, size and shape – can be easily changed by editing the vector layers or smart objects included in the designs.
