# Interchange vs SendMyEbook

The clearest difference is rating: SendMyEbook at 5.0 against Interchange's 4.3. SendMyEbook also leads on monetization model (free with in-app purchases vs subscription). Interchange's advantage is ratings volume (212 vs 1) and review sentiment (73% vs 57%). On price, ads, in-app purchases 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 and SendMyEbook sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

SendMyEbook holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Interchange has 212 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 73% of Interchange's written reviews are positive against 57% of SendMyEbook's, so the app with the better star average is not the one people write more warmly about.

Interchange ships an update every 6 days, SendMyEbook fortnightly. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
