# Amazon Kindle vs Interchange

The clearest difference is rating: Amazon Kindle at 4.9 against Interchange's 4.3. Amazon Kindle also leads on in-app purchases (none vs 10) and ratings volume (5.9M vs 212). Interchange's advantage is update cadence (every 6 days vs fortnightly) and iOS requirement (12.2 vs 17.0). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Interchange sells 9 in-app purchases, starting at $2.49 per month. Amazon Kindle asks for nothing beyond the download.

Amazon Kindle holds the better App Store score, 4.9 against 4.3. That said, the two scores are not equally well evidenced: Amazon Kindle has 5.9M ratings behind it against 212, so its average is the more settled of the two. Written reviews complicate that: 68% of Amazon Kindle's written reviews are positive against 73% of Interchange's, so the app with the better star average is not the one people write more warmly about.

Amazon Kindle ships an update fortnightly, Interchange every 6 days. The most recent releases landed on November 8, 2026 and November 6, 2026 respectively.
