My AppIconMaker project lets you resize a large icon to all the different dimensions needed by the iOS App Store, as well as three sizes for Android, with the push of a button. If you’ve used the RedCorners.Forms template to create your projects, you can simply drag and drop the output files into your projects and replace the files. Everything fits perfectly!
