iOS: If you you're using a read-it-later service such as Pocket, Instapaper or Readability, you probably have a long list of articles that you've been meaning to read. Short helps you find articles you can read in under five or 10 minutes.
Short's essentially a counterpart to something like Longform, expect that instead of pulling picks from a bunch of sources, it pulls them directly from the bookmarking services you already use. You can adjust the filters for articles under five minutes or under 10 minutes. The app also comes packed with a handy night reading mode for reading in the dark. Some bookmarking apps have a filter like this integrated already, but Short makes it easy to pull something up quickly when you don't have a lot of time.
