Also thinking about this. Requirements I've identified -- and this is why people give up and just run Emacs on Android:

1. Able to natively edit and view same file type on both devices, be it .md or .org or whatever you choose (there are more apps supporting .md, if you can stomach that)

2. Links must work on both devices! That alone means it's not trivial, even if you have a lightbulb moment and use .md files for access to more apps, together with one of Emacs' filetype-independent links like Hyperbole or Denote, because no .md app will support those links. Conversely in .org, not all apps even support Org-ID links... especially not making it easy to insert such a link.

3. App must have satisfactory editing facilities. I know at least one app that doesn't even let you indent/dedent list bullets...

4. If you use TODO tasks, the app needs to make it convenient to see them at a glance across all files. Many Org apps fail here and either basically assume you have like one "todo.org" file and need no hand-holding, or even if they list all TODOs, there's no way to sort or filter, or it only lets you see them but not toggle them to DONE!

5. If you use a wiki-style workflow such as org-roam, so that you have far too many small files to keep track of, the app needs to make it easy to browse. Many apps fail here, just showing you a file list on the assumption that you even know what your files are named or what's in them. Count your blessings if there's at least a good search facility.

6. Instant & reliable sync. Logseq Sync is too buggy (at least it was in 2023). Things like Syncthing just aren't good enough if you don't also host a server that is always on. If sync conflicts are frequent, I'll be so wary of editing that I stop altogether.
