It is an RSS reader. Like Google Reader was once upon a time. It watches RSS feeds feeds you put in there, and it grabs new articles in the feed (like any other RSS reader). This gives you a copy of an article in a stripped down view saved inside FreshRSS. You can also add things to a feed's settings like the CSS ID or Class a site uses for their articles, to control what it grabs from the site. Super great app.
