I’ve recently started moving back to RSS as a way to consume news (rather than relying on Twitter). ReadKit is the app I am currently using on macOS. It works with Instapaper, Pocket, Pinboard, Feedly, Fever, NewsBlur, Feed Wrangler, Feedbin, and regular RSS feeds.
ReadKit has lots of various themes so you can customize the look to match how you want it. You can also easily share items to other services (social networks, etc). Overall, it’s a fantastic app!
You can download it on the Mac App Store for $9.99
