This is awesome! I made a similar app that works with a kindle and your mobile device: https://msolomon.github.io/solarwriter-website

Oh yes, I also had a couple of such design - used an app or a server, ssh connection or simple websockets. But for this one I really wanted it to work standalone !

Cool!

Some observations:

The link to the developer homepage in the iOS app store points to msol.io (which appears to be broken/recently registered).

The app is lacking a privacy policy.
