Verdict
The clearest difference is review sentiment: Devil Twins at 87% against Devil Book's 58%. Devil Twins also leads on iOS requirement (8.0 vs 15.0). Devil Book's advantage is ratings volume (1.3K vs 30) and rating (4.8 vs 4.6). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Devil Twins sells 10 one-off in-app purchases and Devil Book sells 13 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Devil Book holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Devil Book has 1.3K ratings behind it against 30, so its average is the more settled of the two. Written reviews complicate that: 87% of Devil Twins's written reviews are positive against 58% of Devil Book's, so the app with the better star average is not the one people write more warmly about.
Devil Twins ships an update every 2 weeks, Devil Book every 9 days. The most recent releases landed on September 18, 2026 and September 3, 2026 respectively.
