I actually am in the same position as you - my main text editor is Emacs (well, doom-emacs). After trying out Bear, Standard Notes etc, I couldn't give up editing plain md files that easily. Org-mode is amazing, but the attachments story is just not solved, especially once you throw mobile into the mix.

I've settled on Joplin, as it's the only serious note-taking app that allows for Emacs-friendly workflow by simply using external editor. I just set the external editor command to be 'emacsclient -c'. Now, when I'm editing a note, I just press Cmd-e, and get Emacs for editing - just for that note. Once I finished editing, it's "C-c k", and Emacs closes and I'm back in Joplin.

I actually set Joplin's layout to always show the rendered md, so that it's basically a pretty front-end for my Emacs-powered editing workflow. Beyond that, syncing and attachments are what makes it more or less perfect second brain system for me.

Have you looked at Orgzly, and if so why didn't you go for it? I'm asking because I'm considering switching to Org mode for notes and looking for a good android client.

I use Orgzly and find it quite nice.

The main difference seems to be that Orgzly is a native Android app, while Organice is a (self-hosted) web service that happens to render nicely in a mobile browser.

I didn't to run a a whole separate server just so I could edit my org-mode files from a phone, so I like Orgzly better. But YMMV.

Lately I am trying to migrate to just running the native emacs on my phone with Termux :>

You're right that Orgzly is a native app, but you're spot on in that organice just happens to render nicely in a mobile browser. You also don't have to run a 'whole separate server' to use it.

organice is a progressive web app and specifically built for that purpose. More on this in the docs: https://organice.200ok.ch/documentation.html#orgcc693e5

As for the installation of it, there's no server required. More on this in the docs: https://organice.200ok.ch/documentation.html#orgfa38071

Having said that, please continue to use whatever works best for you^^ I just wanted to clarify these points.

I think writing/updating org-mode notes from mobile just doesn't have the good UX that I'd want. (Not as mobile-friendly as other apps; and not as easy to use or as powerful on a mobile as on a computer because of the limited form-factor).

I don't use mobile frequently for updating notes or scheduling things; so I can live with using some other app (e.g. OneNote/Sticky Notes) for inputting things on my phone, then refiling that on my computer into org-mode.

I think Orgzly supports a read-heavy usecase like that quite well, since you still get to use org-agenda, have hierarchical notes to view, etc.

I just started using orgzly and it synced really well with Nextcloud over webdav. I'm impressed with it overall.

I am on iOS so can’t try orgzly unfortunately.
