Downloading sleepsoon 3.0.3 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. This free software for Mac OS X was originally created by HarrisonAffel. We recommend checking the downloaded files with any free antivirus.
From the developer:
SleepSoon is designed to act as a countdown timer, setting your computer into sleep mode once complete. The application is useful for limiting your time on the computer, or when you want to shut down your computer after a long download or transfer process.
