This is what finally replaced Google Keep for my shopping list and then eventually everything else. I use Markor and Syncthing on my phone, and a standard text editor on my various computers. It is super nice especially to be able to organize the directory using standard file management tools, search using grep and friends, etc. There is something to be said for simplicity.

+1 for Markor, also available on fdroid

I use markdown too, in a git repo - mainly so I can access them from anywhere, but versioning is occasionally useful too.

Exactly, I wanted something more structured. The filesystem doesn't give me any organizational tools that I want.

My point is to see how easy it is to set up (I used to always equate PHP with having to get a whole WAMP stack online) thus how easy it is to try for yourself.

If you use vscode you should look into the dendron add-on.
