Nightcap

About Nightcap

Nightcap is a sleep timer for your computer, like the one on your TV. Start a 15, 30, 45, 60 or 90 minute timer (or a custom length) straight from the menu bar. As time runs out it slowly dims the screen and lowers the volume, so the show you fell asleep to trails off instead of cutting out, then puts your Mac to sleep, hibernates or shuts it down. Pause, add 15 minutes or cancel from the same menu. Cancel or wake the computer and brightness and volume go back where they were. Free and open source (MIT or Apache 2.0), works offline, no account needed. Also on Windows and Linux.
