Don't want the device screensaver to go on when using applications like speedometers, timers, etc.? BackLighter does just that.
BackLighter disables the screensaver from dimming the device while the application is left running and set to ON. The screensaver can be once again enabled by setting the switch to OFF position or by closing the application.
BackLighter also makes it possible to adjust brightness with several convenien settings.
