Unread: An RSS Reader App - App Store
Unread is a fast, typography-focused RSS reader app for iPhone, iPad, and Mac that syncs across devices and integrates with multiple feed services like Feedly, Inoreader, and Miniflux. Version 5.0 adds improved image handling for article thumbnails that intelligently crop around faces and salient details, expands syncing support to FreshRSS and Miniflux via their native APIs, and includes a bulk "mark old articles read" feature to manage feed backlogs. The app is free with optional $29.99/year subscription for advanced features like saving to read-later services, caching for offline access, and custom shortcuts.
I used the /design on Athenana and it worked pretty good. I will say that you need to go through and do a very deep visual check, as things won't be perfect, but the overall effect is nice. I'm still searching for a slightly better font to use, but otherwise, I'm happy with the output!
