This is so close to my idea for the ideal note-taking app (that I never tried to make). I discovered it a couple of months ago and used it to plan a trip around Europe: research and write up on desktop, refer and make quick changes on phone. The monetisation options are incredibly user-respecting too. Although I don't need the Pro features, I'm on the monthly subscription just to support the project.
