Yattee is probably the closest equivalent.

Sadly this is a known iOS PWA issue. Nothing wefwef can do about it. Hopefully it is (or will be) fixed in iOS 17.

I much prefer "Truppen-Ursel" ("Troops Ursel" I guess)

Good time to be McKinsey I guess ...

The "blocks more ads" part is probably mostly because AdGuard allows you to add the "normal" blocklists that you find all around the Internet (plus it has a large collection of built-in ones already).

IIRC 1Blocker uses its own format, which isn't as prevalent.

I use AdGuard. Used it for years - with brief stints of 1Blocker - and I feel like AdGuard blocks more ads and breaks less sites.

I use NixOS on all of my servers.
