Great template for Sketch if you want to work with icons. It includes a great grid and a properly rounded app icon. It's all matching the release verison of iOS 7. It has both 512x512 (iTunes Artwork) and 120x120 (iPhone Retina).
Feel free to use it for whatever. Might want to follow me if you want similar stuff in the future, I'm always going to create it for myself and share it afterwards.
