Verdict

The call

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.

CostPrice · In-app purchases · Ads · Monetization

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

Interchange ships an update every 6 days, SendMyEbook fortnightly. The most recent releases landed on October 29, 2026 and October 28, 2026 respectively.
