The Icon Factory has a kickstarter fund for an app that would wrangle your feeds on iOS

Tapestry would pull your many feeds together and sort them by timeline.

I'm still trying to decide whether I want to back this. I like Icon Factory. They do good work. I just don't have much beyond RSS and Lemmy to wrangle.

But I did think people might be interested as this will support Mastadon and I know there's some overlap among us.
