I’m not at all affiliated with Joplin as I just stumbled upon this beautiful piece of software a while ago.
In a nutshell it works on the 3 major platforms, it synchronises with the major cloud providers and even with owncloud. And last but not least it works from the command line! For a professional the latter is a real timesaver. If you don’t know it or you did not already hurry to google it, go now to https://joplin.cozic.net/terminal/ for command line setup instructions and to https://joplin.cozic.net/ for desktop setup instructions. Keep the good work going guys!
