I’ve been using CloudFlare for my DNS registration. They’re incredibly cheap (I think they sell at or near wholesale rates).

For hosting, I tend to use Dreamhost. I think that it’s about $100/yr, with unlimited email inboxes, unlimited bandwidth (no porn or video hosting, or other things like that in the TOS).

Personally, I use Fastmail for my email (and CloudFlare’s email forwarding to forward to it), although Proton is pretty good to look at as well.

Yeah, it’s on the Apple app store, and the Android version is available directly from their GitHub release page as an APK, or on F-Droid.

Logseq has an iOS app here, and an Android app at their GitHub releases.

Definitely more. It’s geared to note taking, with hashtags, wiki-like linking, and loads of other features. The main page is here.

I’m a big fan of Logseq. I use Syncthing to sync a folder between my desktop and phone and it works great. Tagging, everything is in markdown, and it’s easy to navigate around.

Maybe have them coalesce based on channel name, but have local mods on each server. It’d be great if you could share moderation between trusted servers or trusted mods on different servers as well (this could be on a per-community or per-server basis).
