I offer very clean design of iOS app icons. Each icon has a detailed design progress. Starting from description of app service, think about end product and design right metaphor. Going through sketches and continue with very detailed graphics.
I believe simplicity is beauty. Each icon has to be clean and good to recognize even in small sizes. Right metaphor is a key.
I provide icon in all sizes by Apple Icon Guidelines in .png format. PSD file is included too.
