Want to display a clock on your phone at night but don't want to burn your screen with a stationary image? Then maybe this app is for you.
Clock Screensaver is a simple app that, when your device goes idle while on AC power, will display a moving digital clock. This is useful if you don't want to have to push a button in order to see the time at night. The clock moves around the screen so as to not cause any permanent screen burn-in.
*Animation - Scroll up/down/left/right or bounce randomly around the screen.
*Force Landscape Orientation
*Allow When Off AC
*May prevent your device from locking automatically, although you can still lock it manually.
*Screensaver activates when the screen turns off, so you must have your screen set to turn off automatically in order for the screensaver to activate automatically.
