Download of SlothCam 3.44 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The software lies within Lifestyle Tools, more precisely Entertainment. We recommend checking the downloaded files with any free antivirus. This free software for Mac OS X was originally designed by Jackson.
From the developer:
