This is software that helps to find you good quality torrents, schedule them for downloading, and helps ease the tedious process. In other words, it just streamlines the whole process of torrenting.
All you have to do is find the torrent file like a movie you want to download. Add it to your couch potato and the download will start automatically. You can even use Usenet for downloading files using apps like SABnzbd.
Iseedfast has Couch Potato pre-configured for you with a one-click installation.
