# LuckRing vs Kitten mew

The clearest difference is in-app purchases: Kitten mew at none against LuckRing's 5. Kitten mew also leads on rating (2.4 vs 2.1) and iOS requirement (13.0 vs 15.0). LuckRing's advantage is update cadence (every 3 weeks vs every 3 months) and ratings volume (348 vs 31). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. LuckRing sells 5 one-off in-app purchases. Kitten mew asks for nothing beyond the download.

Kitten mew holds the better App Store score, 2.4 against 2.1. That said, the two scores are not equally well evidenced: LuckRing has 348 ratings behind it against 31, so its average is the more settled of the two. Written reviews complicate that: 22% of LuckRing's written reviews are positive against 20% of Kitten mew's, so the app with the better star average is not the one people write more warmly about.

LuckRing ships an update every 3 weeks, Kitten mew every 3 months. The most recent releases landed on October 27, 2026 and October 24, 2026 respectively.
