If you create Apps for the iPad, iPhone, or Android devices, you are faced with the tedious task of creating App icons at various sizes. In order to submit an iPad app to the App store, for example, you need to submit your App icon in PNG format in seven different sizes.
To make this process much, much easier, Johannes Henseler has created a free Photoshop template. To use the template, you open a smart object on one of the Photoshop layers, and create your artwork in Illustrator or Photoshop in the smart object. Then, with a single click you can export icons in 15 different sizes all at once. Thanks Johannes!
If you've previously used this template, note that Johannes updated the template on 6/22/2012.
