Can anyone recommend an app for iPad that will allow you to design custom sized logos or banners? I downloaded Photoshop Touch which is amazing but you can't start with a blank canvas like you can on the desktop version. I'd like the app to allow me to pick a length and width in pixels and give me the blank canvas to draw, import pictures add layers etc but can't find any. I did try Easy Graphics but found it hard to use. Any suggestions are greatly appreciated.
