# Q... vs テイペンリバーシ

The clearest difference is rating: テイペンリバーシ at 3.7 against Q...'s 2.7. テイペンリバーシ also leads on update cadence (every 3 weeks vs every 3 months) and iOS requirement (13.0 vs 15.0). Q...'s advantage is ratings volume (81 vs 3) and review sentiment (51% vs 40%). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Q... sells 4 one-off in-app purchases and テイペンリバーシ sells 11 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

テイペンリバーシ holds the better App Store score, 3.7 against 2.7. That said, the two scores are not equally well evidenced: Q... has 81 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 51% of Q...'s written reviews are positive against 40% of テイペンリバーシ's, so the app with the better star average is not the one people write more warmly about.

Q... ships an update every 3 months, テイペンリバーシ every 3 weeks. The most recent releases landed on October 19, 2026 and October 14, 2026 respectively.
