I'm just using Google Drive with the files the app uses on Windows and mobile (using FolderSync for Android). I'll probably try out the git plugin soon so I can use it easily with Linux but was trying to use Obsidian without and additional plugins for a while as I'm just trying it out.
I did it just fine for the cost of the license of Working Copy syncing to a iCloud folder. But the Obsidian license still made me end up going over to LogSeq, which works better for my mental model.
i am hoping, like onenote, a note taking system that i can use on computer and mobile devices and sync to each other, easily. This is very natural need.
Or syncthing. I already had it set up between phone, pi and PC, so threw the notes dir into there. Now free to switch between desktop and mobile with quasi instant updates.
This is turn down 100%.
