You can use Feedly for free, with some sponsored ads, though you’re limited to 100 feeds and three folders for those feeds. Adding new feedsYou can follow sites and topics in Feedly. Boards in Feedly work a bit like Pinterest or Flipboard, letting you curate articles of interest in a different way to folders. Other options on the left-hand navigation bar also let you search through your feeds for certain keywords, and see articles you’ve recently read. Paying Feedly users can also annotate articles inside the app: There’s an Add note button that appears as you open up each story.
