Web Feeds are used to automatically follow changes on websites that you are interested in.
On the World Wide Web, a web feed (or news feed) is a data format used for providing users with frequently updated content. Content distributors syndicate a web feed, thereby allowing users to subscribe a channel to it by adding the feed resource address to a news aggregator client (also called a feed reader or a news reader). Users typically subscribe to a feed by manually entering the URL of a feed or clicking a link in a web browser or by dragging the link from the web browser to the aggregator, thus “RSS and Atom files provide news updates from a website in a simple form for your computer.”
Inoreader is a web-based content and RSS feed reader, a cloud-based service for web browsers and mobile devices running iOS and Android. It compiles news feeds from online sources for the user in unified layout to customize and share with others. Inoreader was first released by Innologica in 2013.
