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.

I didn’t see a paywall when I clicked on the link, but you can try this:

Labors reader looks really great. Just wish it had an iOS/android app. I’ll definitely keep it in mind.

See if this works: https://12ft.io/proxy?q=https%3A%2F%2Fwww.telegraph.co.uk%2Fbusiness%2F2023%2F07%2F13%2Fwhite-hydrogen-disrupt-global-energy-net-zero%2F

I didn’t see it listed in the comments but Stopthe Madness is the best extension I use, helps with YouTube but also other sites:
