# Devil Book vs Slime Evolutionary Path

The clearest difference is rating: Devil Book at 4.8 against Slime Evolutionary Path's 4.4. Devil Book also leads on update cadence (every 9 days vs every 3 weeks). Slime Evolutionary Path's advantage is review sentiment (84% vs 58%) and iOS requirement (12.0 vs 15.0). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Devil Book sells 13 one-off in-app purchases and Slime Evolutionary Path sells 5 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 4.4. Both are backed by a comparable volume of ratings — 1.3K and 765 respectively. Written reviews complicate that: 58% of Devil Book's written reviews are positive against 84% of Slime Evolutionary Path's, so the app with the better star average is not the one people write more warmly about.

Devil Book ships an update every 9 days, Slime Evolutionary Path every 3 weeks. The most recent releases landed on October 7, 2026 and October 11, 2026 respectively.
