This is an App Icon Template that, through Smart Objects in Photoshop, attempts to automate the process of rendering the various sizes that needs to be bundled with iOS Apps.The idea is to edit the largest size and have the smaller sizes automatically rendered enabling a much quicker workflow when designing icons. You’ll also find a selection of ready-made textures that you can build on and easy export actions that spit out the exact files you need to deliver to Apple.
I stumbled upon this whilst working on an icon for a project I’m doing and it’s pretty freaking awesome. The icon layout is there but what’s more is that the PSD automatically generates all the required sizes and shows you what it looks like on an iOS home screen and in the App Store. Fantastic.
