I'm one of those that cited it as literally one of two apps that I will never switch to iOS over. I sincerely hope the community picks it up and continues it. It's easily one of the best apps I've ever used.
Same here. Been on android for several years now mostly because of Tachiyomi (and also KeepassDX, which is an amazing keepass implemenation for Android. I recommend you check it out if you are a keepass user).
Which apps? Maybe KOREADER, eInkBro, Infinity for reddit? On iOS side I love Overcast for podcasts.
Vanced/ReVanced is the other. Cannot stand using YouTube without adblock and sponsorblock.
Yattee on iOS is pretty good. It connects to Piped and Invidious instances.
