I am trying to slowly de-Google-ify myself by moving to open source apps, I wanna ditch google notes and evernote. I tried obsidian, standard notes, and joplin, I liked using obsidian on PC and standard notes looks nice on android but obsidian you need to pay to have sync and standard notes doesn't do markdown unless you pay (are plugins only on PC???). Joplin has most features I need but I don't like how it looks/feels on android (haven't tried in PC yet)

Basically what I want the most in a notes app is offline with sync capability for phone and PC, would be nice to make folders for notes like notepads on evernote, and md is a big plus but I can live without it. I would love if I could use something like proton drive for cloud sync and wouldn't mind paying for obsidian if it was cheaper cuz $8 per month is too much for my minimum pay and I didnt see any cheaper plans.

EDIT: If no one has any better suggestions, I am thinking of trying to setup obsidian with syncthing.
