Screensaver Clock is a free Android app developed by hosinoatusi that can display a digital clock on your phone's full screen without any status bar or title bar. The clock changes its location little by little, making it a great option for those who want to use it as a table clock for a long time without having to worry about burning the screen.

One of the best features of Screensaver Clock is that you can freely set the color and brightness to be displayed. This means that even if you put it on your bedside in the middle of the night, it will not disturb your sleep. The app is simple and easy to use, with a minimalist design that is perfect for those who prefer a clean and uncluttered interface.
