I have been using Unread 2 for a couple of weeks as my RSS reader and it has become my favourite RSS reader.
Unread is beautifully designed. It looks great and it is a joy to use. One handed on my iPhone XS Max everything is reachable. I can swipe back and forward all day.
Unread's article list view cleverly adapts the summary text to provide one or two full sentences, depending on the length. It's a simple feature but makes a huge difference when deciding on reading the whole article or not.
Unread provides a variety of themes and app icons. I really like dark themes with a tint of colour like dark greys or a good blue. Think the blue "dim" dark mode on the iOS twitter app. I am using the Panic theme in Unread and it looks great.
As a bonus, I have figured how to use Unread as a "read it later" app too. By installing the Feedly app (which is the RSS service I use) I can save articles to the "Read Later" board via the iOS share sheet, this then syncs to the "Saved" area in Unread.
Unread is a great app and though it took me a while to commit to the subscription (AU$29 per year) I am very happy with my purchase. If you use RSS daily, I could not recommend it more. There is a 50 article free trial, which does give a good feel for the app except its great background syncing
