App Icon Template is an icon design toolkit for creating iOS app icons faster and easily.
The kit includes a .PSD + .ATN (Adobe Photoshop Action) file where the .PSD comes with useful layers like the rounded corners, gradients and even various background textures.
Smart objects are used to automate the generation of multiple sizes and, once the design is saved, the template instantly displays the same icon in multiple sizes.
The PS actions included generate every needed file, both in squared (no transparency, to be used in the app) and in rounded versions (for other design uses). The files are automatically named after the Apple HIG so they’ll be good to deliver instantly.
