Our icon packs have icons for most popular apps. We are updating and adding new icons all the time. The specific number of icons varies per pack. If you are missing an icon, you can use the request feature within the app to let us know what app you would like us to add. Icon packs are not designed to theme every single icon on your devices. They are designed to allow you to make a beautiful home screen.
We understand the question, of course. But, really, to get a feel for the exciting changes you can accomplish on your phone, give one of our packs a try. We think you'll be pretty thrilled with the results.
