Feed Wrangler recently announced that it is shutting down on March 1, 2023. Standalone accounts will be available before Feed Wrangler shuts down. If you are using Feed Wrangler and are using it only as a backend for Unread, Unread’s standalone accounts will provide a suitable replacement. If you also sync to other RSS readers or if you also need a web interface, Unread supports Feedbin, Feedly, Inoreader, and NewsBlur.
Don’t see myself moving away from Reeder, but Unread is a great app with beautiful reading modes. Good alternative.
