Verdict

The call

The clearest difference is rating: Devil Book at 4.8 against Rabbit Empire's 4.5. Devil Book also leads on ratings volume (1.3K vs 67). Rabbit Empire's advantage is iOS requirement (11.0 vs 15.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Devil Book sells 13 one-off in-app purchases and Rabbit Empire sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Devil Book holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Devil Book has 1.3K ratings behind it against 67, so its average is the more settled of the two. Written reviews complicate that: 58% of Devil Book's written reviews are positive against 64% of Rabbit Empire's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Devil Book ships an update every 9 days, Rabbit Empire every 5 days. The most recent releases landed on October 22, 2026 and October 21, 2026 respectively.
