Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Kotobee

  • Interactive EPUB 3 features degrade or disappear in mainstream retail readers, Kindle in particular, so a book built around widgets and quizzes cannot simply be resold through ordinary retail channels later.
  • Exporting a native app does not remove the app store obligations: you need Apple and Google developer accounts, you handle review submissions, and you own every rejection and update cycle.
  • There is no print workflow at all, so a title that also needs a paperback edition requires a separate layout tool and a duplicated production process.
  • It is a small vendor with a limited partner and integration ecosystem, which is a genuine concern for an institution embedding it in a multi-year curriculum programme.
  • Cloud hosting, DRM and user management are priced separately from the authoring licence, so the recurring cost of delivery, rather than the software purchase, is what the budget has to carry.

Moon Reader

  • It is Android only, so it is not an option for iOS, Kindle hardware or desktop-first readers.
  • It sells no books itself, so it is only useful to someone who already has an ebook acquisition method, whether purchase, library OPDS or personal files.
  • The interface and settings menus are dense and dated compared with polished store apps like Kobo or the Everand app.
  • Development has slowed at times, and users have reported gaps between updates for newer Android versions.
  • There is no cloud account tying your library and progress together across devices beyond what you configure manually via Dropbox or Drive.

Answered from the vendors’ own pages

Kotobee: Can I sell a Kotobee book on Amazon?

You can sell a stripped-down EPUB, but the interactive content that justified the tool will not render. Treat retail as a separate, simpler edition.

Moon Reader: Does Moon Reader sell books?

No, it only reads ebook and comic files you already have or add via OPDS, cloud storage or local files.

Kotobee: Does Kotobee publish the app to the stores for me?

No. It generates the application; you supply the developer accounts and go through Apple and Google review yourself, including every subsequent update.

Moon Reader: Is there a subscription?

No, Moon Reader+ is a one-time purchase; there is also a free ad-supported version.

Kotobee: Is it suitable for a trade fiction publisher?

No. It is built for education, training and reference material where interactivity and controlled access are the point.

Moon Reader: Is it available on iOS?

No, Moon Reader is Android only.
