# Duel Revolution vs Kaetram

The clearest difference is rating: Duel Revolution at 4.7 against Kaetram's 4.0. Duel Revolution also leads on ratings volume (455 vs 57) and iOS requirement (13.0 vs 17.0). Kaetram's advantage is review sentiment (72% vs 63%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Duel Revolution sells 7 one-off in-app purchases and Kaetram sells 13 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

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.

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