CallLauncherFree is a launcher for Android devices that can be launched via the home button, search button, or call button. It allows for quick app switching, even while using other apps. This launcher can be launched with a two-touch call button and number key combination on devices like the Softbank 007SH, while other devices can launch it with a tap.

The launcher sheet can be customized with app icons that can be launched with number keys. The first row of the launcher features three icons for the mail key, call key, and web key. These can be customized with the apps of your choice. The launcher sheet can be switched with a flick or the * key or # key, and shortcuts to each sheet can be added to the home screen.

The paid version of CallLauncherFree includes additional features like the ability to place bookmarks and other shortcuts on the launcher sheet, the ability to customize the icon and label of each shortcut, and the ability to customize the behavior of keys and flicks. Additionally, the launcher displays free memory and battery life on the title bar, and a guide for launching icons with number keys can be toggled on or off.
