As John and I recently discussed on AppStories, there's never been a better time to use RSS. There are several powerful services to choose from (we both like Inoreader), and the selection of modern RSS clients for iOS is also solid these days.
Unread, now developed by Golden Hill Software, is one of the more elegant options based on comfortable gestures and a focused reading experience. I linked to the app in November when it received support for the iPhone X and iPad multitasking; in the post, I noted that I still wanted to see Unread gain Inoreader integration and haptic feedback on the latest iPhones.
With version 1.9 released today, Unread now fully supports Inoreader and plays subtle taps for different kinds of swipe gestures. Syncing subscriptions with Inoreader supports the full range of options available on the service: in addition to unread and starred articles, you can view your active searches, browse websites by folder, or open articles for individual subscriptions. Along with the aforementioned Taptic Engine integration, I also want to point out that Unread 1.9 supports one of the lesser known Safari View Controller features on iOS: in the app's settings, you can now enable an option to load Safari View Controller in Reader mode by default when you tap any link in the app.
Unread isn't my default RSS client (I use Fiery Feeds 2 now), but I keep the app on my devices when I feel like I want to take a more relaxed approach to reading articles I've starred.
Unread 1.9 is available on the App Store.
