Where each one falls short

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

Kobo Writing Life

  • Kobo overall market share is smaller than Amazon Kindle in the US specifically, so an author relying only on Kobo reaches a smaller US audience than KDP alone would.
  • Automatic price matching to other retailers means an author discounting on one platform can see their Kobo price change without a deliberate action, which requires active monitoring to avoid unintended royalty impact.
  • The requirement to price at least 20% below any physical edition to qualify for 70% is easy to overlook and can silently drop an author into the 45% tier if a print edition price changes without an ebook price adjustment.
  • Below the qualifying threshold, the fallback royalty is 45%, not the 35% floor on KDP, which sounds better but is a smaller total addressable audience given lower Kobo market share, so gross revenue comparison still favours evaluating both platforms together.
  • As with any single-retailer self-publishing tool, relying solely on Kobo concentrates risk in one platform policy and market position rather than spreading across a wide-distribution strategy.

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.
