I'm not much of a note taking person, but occasionally I do need to scribble down some thoughts, store it and have it synced to my devices.
I used to use Obsidian, but since I don't use the app regularly it tends to either log me out or stop syncing at all.
I also tried Affine, but ... one time I had to take notes for work and copied some lines of code into the note, and the app became unresponsive.
Recently, I came across notesnook and have been hosting it for quite a while now, and it's excellent. The sync to the Android app works reliably well.
So a big thx to the devs.
