NIWO Software has introduced NIWO Slumber, a tool/timer for Mac OS X. It’s available at the Mac App Store for US$1.99 until April 19; after that it’s $4.99. A demo is available at the NIWO Software website (http://www.niwosoft.com).
NIWO Slumber can shutdown, restart, sleep or logout your computer at any given time. It can be used to turn off your Mac at night or when you want to make a break at a given time. NIWO Slumber comes with integrated presets and the ability to create and manage your own templates.
The app reminds the user that there’s a timer running. You can set up the Time (5, 10, 15, 20 , 25, 30 minutes before) and type of notification (only Notification, or a Notification with Sound). NIWO Slumber supports Growl as well.
