iOS: RSS readers have a nasty habit of favouring the new and overwhelming feeds that don't update as often as others. Slow Feeds solves that problem.
For the most part, the app is a straight-forward RSS reader. However, it has one specialised tab that aggregates "slow feeds" (get it?). These are the sites that update less often and are most likely to get lost among the noise. It's a subtle but helpful distinction if your reader is filled with hundreds or thousands of articles per day.
