This is a live wallpaper for your home screen that displays the Android activity log. It is a must-have for geeks. It includes several fonts, an 'old phosphor effect', and other options. It works on rooted devices only. It displays the logs of the current application in the activity window. If you use a non-rooted device, only the logs of the app itself will be displayed, which is not very interesting.

Logcat is a free live wallpaper, but in order to use it, you need to grant it access to the drawable folder. It does not access any other files or folders.
