Oh nifty. Joplin seems to have auto-save now (probably had it for a while already, haven't checked in years). Might give this a try again, need a good note taking app.
@trinsec I run effectively the same (ownCloud). Those above apps work very well for me: Markor (Android) + QOwnNotes on Desktop (Obsidian has some nicer plugins, like Mermaid integration, etc.)
@FailForward Thanks, I'll take a peek at it!
@FailForward NextCloud (self-hosted) & Web, Android, and preferably a Windows desktop version too. Markdown is fine, should be able to have images embedded too.
