The 3.1 version of Never Read for Mac was available to download on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe.

From the developer:
Never Read is the Mac app to help clear unread articles. It will save you from the pressure of a huge backlog of articles. The application will delete automatically unread articles that are older than 30 days (or any number of days you specify). If you would like to keep selected articles from being deleted, simply archive or favorite them. Never Read is designed to only delete items in your "unreads" list that are not favorited.
You may want to check out more software for Mac, such as Read One, Speed Reading or Cisdem Document Reader for Mac, which might be related to Never Read.
