Although Goodnight Timer promises to shut down your computer at a set time, it failed to do so in our tests.
The interface is bland but easy to understand, allowing you to choose a specific time or set a countdown timer for the shutdown to occur. There's also an option to fade audio volume over time. Although most users would probably be happy with a simple control to fade the music gradually, Goodnight Timer offers two options (linear and exponential). It also includes a simple graph that charts your selected volume control options, which seems like more information than is necessary.
While Goodnight Timer's audio controls proved effective, the program consistently failed to shut down our test machines. Even when the program was set to force a shutdown, it still didn't work. Although offered free of charge, Goodnight Timer's faulty performance makes it a bad deal for any user.
