If u want to just design its no need to know HTML, CSS or other language. Just design in Photoshop as your requirement. Programming part is done by programmer. Layer is most important for slicing in web or apps design . So make every shape in different layer. It is also important to make a pixel perfect design. Search in Google for ur device resolution. Normaly IOS apps design need to 5 different size for 5 different device: 640×1136 px 640×960 px. 320×480 px. 1536×2048 px. 768×1024 px.
I have no idea about Android.
