HOW SURE ARE WE
Lower confidence: this app ranks below the overall top 50 everywhere, where single estimates can be off 2 to 4 times. The range is wide on purpose. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

WHAT THEY ASK FOR
  • Sometimes the software gets stuck on the same section and needs a quick restart to get back on track. 4★, Oct 12, 2026
  • I wish they'd hire people to read these instead of trying AI. 3★, Sep 15, 2026

  • I didn't need a subscription since I already have dozens of books in my Kindle library. 5★, Aug 14, 2026
  • It would be nice to have the audio version, but for me it isn't essential. 5★, Aug 8, 2026
  • I wish I hadn't spent the money on it.But now I have, so I'll just deal with it.Save yourself the money pick a different app 2★, Aug 3, 2026
  • It would be great if the AI knew how to sort out typos...for example there have been several time where the word my was typed 'ny' and the AI narrator said New York instead of 'ny' 4★, Jul 22, 2026
  • I wish on preload it didn't save by the page. 4★, Jun 28, 2026

Lovely read of my kindle library .

★★★★★Oct 20, 2026

this is not good. the AI can't read common words correctly. it doesn't understand sentence structure. it also randomly skips back & starts playing a section it's already played. reaching out to the developers/contact for support resulted in absolutely no response. it's basically unusable bc it's so bad.

★★★★★Oct 20, 2026
