RootDim was formerly known as SuperDim. RootDim requires root privileges on your device. RootDim has been largely superceded by our ScreenDim, which does not require root (though it also has an enhanced root mode, which on some newer devices may work more reliably than RootDim) and has useful features like presets in the notification area.
