I have OneNote on my phone. How is Cubeit better? Displayed as cards isn’t enough. Collaboration isn’t important to me. I can collaborate on OneNote, but I generally find most people prefer their own notes (except at work, where we have to use corporate approved software only).

What features would I want? Low friction. Come up with a way to get content in and out easily, and optimize my text and pictures for mobile. Then I’m interested. I would probably even prefer if you had a dedicated browser in the app so you could completely control the experience.
