I use Fluent Reader but I have to admit it’s a bit janky in terms of UX. It also doesn’t have built in feed discovery like inoreader but at least its (ad)free. It does its job well enough.
That’s what I used twitter for tbh. Since everyone is on it it’s easy to follow people, get instant updates and maybe even discover something new through the people you follow and their likes. It’s really a shame it went to shit, it was the lurkers perfect tool, especially when it comes to artists or content creators.
IIRC the web app had some intrusive ads(hard to remove and taking a bug chunk of screen space), is the offline version any better?
