I’ve never tried Booklore (glad of that now!) but what were the greatest benefits over something like Audiobookshelf (what I currently use)?

I use Reeder (https://apps.apple.com/app/id1529445840) on my iPad and iPhone. Before it allowed you to subscribe I was using Feedly.

I use it for digital books and it works great. You can configure it to send a book to an email so it appears automatically. The auto tagging works well too.
