Great suggestions. I'm quite happy with Obsidian on Linux, especially due to great plugin ecosystem. Granted that it would have been great if the clients were open-source; but Obsidian is one of those non-FOSS apps which are so consumer oriented that they get an exception from me. I sync the files from Obsidian using syncthing to Android & use Markor for editing. But this wouldn't be possible on iOS.
