Verdict

The call

The clearest difference is in-app purchases: Rah Book Reader at none against Amazon Kindle's 12. Rah Book Reader also leads on iOS requirement (13.0 vs 17.0). Amazon Kindle's advantage is update cadence (fortnightly vs every 5 months) and ratings volume (5.8M vs 9.1K). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Amazon Kindle sells 12 in-app purchases, starting at $13.99 per month. Rah Book Reader asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Amazon Kindle holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Amazon Kindle has 5.8M ratings behind it against 9.1K, so its average is the more settled of the two. Written reviews complicate that: 68% of Amazon Kindle's written reviews are positive against 72% of Rah Book Reader's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Amazon Kindle ships an update fortnightly, Rah Book Reader every 5 months. The most recent releases landed on September 25, 2026 and September 24, 2026 respectively.
