The short version

  • Each has a real cost: Kindle Direct Publishing the 70% royalty band has hard edges: pricing even one cent outside $2.99-$12.99 drops the royalty to 35%, which is a cliff, not a gradual scale, and easy to trigger by accident when adjusting price for a promotion.; Moon Reader it is Android only, so it is not an option for iOS, Kindle hardware or desktop-first readers.
  • They diverge on capability: Kindle Direct Publishing covers Free publishing, Moon Reader covers Broad format support.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Kindle Direct Publishing

  • The 70% royalty band has hard edges: pricing even one cent outside $2.99-$12.99 drops the royalty to 35%, which is a cliff, not a gradual scale, and easy to trigger by accident when adjusting price for a promotion.
  • The delivery fee, roughly $0.15 per megabyte, is deducted on every sale under the 70% tier, so image-heavy or long ebooks lose meaningfully more revenue per sale than a plain-text book at the same list price.
  • KDP Select exclusivity, while optional, is the only route to Kindle Unlimited page-read royalties, so authors face a real trade-off between Amazon-only reach with page-read income and wider distribution without it.
  • Public domain or primarily public-domain content is capped at the 35% royalty regardless of price, so that category of publisher cannot access the higher rate at all.
  • As a single-retailer platform, an author relying solely on KDP is concentrated in one sales channel controlled entirely by Amazon policy, which has changed royalty terms before (the July 2026 price band expansion is itself an example) and can do so again.

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.
