The app acts as a sort of customization center for your device. From it, you can change your apps' icons and your desktop backgrounds. Just register within the app and you'll be able to download all kinds of content.
In addition to tons of free content, Cocoppa has some packs of icons and backgrounds available for purchase. You'll need to pull out your wallet if you want to gain access to those, but typically they are even more attractive than the free themes.
Cocoppa is a useful tool to make your phone cuter and more child-friendly. It may not be the perfect app for everyone, but plenty of users are sure to enjoy these launchers made by Cocoppa.
Requires Android 2.3.3 or higher.
