I use syncthing to sync my ~/Org directory to my phone and other devices.

Also it is a git repo and I occasionally check everything in and push it to my git server so that it acts as a sort of backup.

There are a few decent Org apps for Android that work with it. I've used Orgzly which is useful for simple notes and todos/agenda stuff. I use it for shopping lists.

However now with Emacs 30.x releases it has a official Android port. I have no idea how good it is. Haven't tried it yet.

My needs are filled with a ultra portable laptop, though.
