I bought a Kobo Clara hd (6") especially for the reason to be able to carry it around in a pocket so that I can always have it on me

What journal app could you run via nextcloud?

Thanks! I downloaded a bunch

As far as I can tell it’s supported, but the colour coding is not

I like it! Too bad it doesn’t have a small summary of the book with it.

You can install KOReader on Kobo. Very nice UI.
