Pocket generates RSS feeds of your saved items, and you can subscribe to these feeds using an RSS reader.
To find your Pocket RSS feed URLs, click here.
If you have a Pocket username (that's not an email address), you can also create the feed URLs yourself using the syntax below:
My List
http://getpocket.com/users/USERNAME/feed/unread
Archive
http://getpocket.com/users/USERNAME/feed/read
All Items (My List + Archive)
http://getpocket.com/users/USERNAME/feed/all
