Searching the Fediverse for new things. Was box464 on Reddit as well, but didn’t post much.
Hmm I can’t think of any, sorry. Surprising, because there’s a mastodon app for just about every scenario you can think of. Hopefully someone else can pipe in with a suggestion.
I’ve got a few for you, but I think they are still in beta. Reach out and you’re likely to get an invite tho! All iOS. Hope you find one that fits.

Can confirm Obsidian works well. The GitHub plugin I’ve used is find, just have to remember to commit and push. Would prefer a save as you go situation.
