One thing I genuinely miss is an app that collects my emails AND RSS feeds in one place. I know that Thunderbird kind of does this on desktop, but there is no Thunderbird for iOS as of yet. And even if there was, what are the chances it’d do exactly that?

Seems like a missed opportunity on Apple’s side.

@preslavrachev I'm testing these days, Screvi https://screvi.com
Thinking of adding newsletters and links in one place. (It doesn't yet beat Raindrop on parsing links info)
Highlights Manager & Read-it-Later App | Screvi

Import highlights from Kindle, Kobo, Apple Books, PDFs, web articles, Twitter/X, YouTube, and physical books into one place. Semantic search, spaced repetition review, a built-in article reader, and browser extension. All the tools you need to stop forgetting what you read.
