Two things have been missing from your iOS applications, the first being the lack of a custom icon. This is crucial for the marketing of your application; you need to bring your application design together to present it to users. When a user scrolls through a long list of possible applications on the App Store, applications with strong icon design stand out. But remember that the user has to look at your application’s icon every time he looks at the Home screen. The icon has to be distinctive to stand out, but it also has to be attractive so that the user is willing to keep your application around. I’ve uninstalled otherwise good applications because I couldn’t put up with their icons, and I’m not alone.
