# Amazon Kindle vs i2Reader Cloud

The clearest difference is rating: Amazon Kindle at 4.9 against i2Reader Cloud's 4.1. Amazon Kindle also leads on update cadence (fortnightly vs every 3 months) and ratings volume (5.8M vs 74). i2Reader Cloud's advantage is iOS requirement (15.6 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Amazon Kindle sells 12 in-app purchases, starting at $13.99 per month and i2Reader Cloud sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Amazon Kindle holds the better App Store score, 4.9 against 4.1. That said, the two scores are not equally well evidenced: Amazon Kindle has 5.8M ratings behind it against 74, so its average is the more settled of the two. Written reviews point the same way: 68% of Amazon Kindle's written reviews are positive against 48% of i2Reader Cloud's.

Amazon Kindle ships an update fortnightly, i2Reader Cloud every 3 months. The most recent releases landed on September 25, 2026 and September 24, 2026 respectively.
