Verdict

The call

The clearest difference is rating: Devil Slayer at 4.8 against Kingdom Quest's 4.6. Kingdom Quest's advantage is ratings volume (343 vs 47) and review sentiment (80% vs 71%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Kingdom Quest sells 10 one-off in-app purchases and Devil Slayer 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 Slayer holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Kingdom Quest has 343 ratings behind it against 47, so its average is the more settled of the two. Written reviews complicate that: 80% of Kingdom Quest's written reviews are positive against 71% of Devil Slayer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Kingdom Quest ships an update every 10 days, Devil Slayer every 3 weeks. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
