CostPrice · In-app purchases · Ads · Monetization

ReceptionRating · Positive reviews · Number of ratings

Duel Revolution holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Duel Revolution has 455 ratings behind it against 57, so its average is the more settled of the two. Written reviews complicate that: 63% of Duel Revolution's written reviews are positive against 72% of Kaetram's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 5 days. The most recent releases landed on October 30, 2026 and October 25, 2026 respectively.
