Ah. Well that sure shuts down the "you don't have to use Emacs" argument.

Because there is no other real option. Mobile org users overwhelmingly (AFAICT) use Emacs in Termux to edit their files.
This post was originally written in 2017 (tools maybe first in 2019? though it hardly matters). It's still true today.
Both apps support Org-mode's scheduling, robust linking, and search features to some extent, features which don't exist at all in Markdown.
But that kind of inconsistency has been my overwhelming experience with anything except Emacs. CommonMark stuff has been practically flawless every time by comparison (though "markdown" in general is absolutely not, that's an unspecified mess)
