# Kitty Q vs The Unstoppables 2

The clearest difference is rating: Kitty Q at 4.9 against The Unstoppables 2's 2.7. Kitty Q also leads on ratings volume (400 vs 3) and iOS requirement (11.0 vs 15.0). The Unstoppables 2's advantage is update cadence (every 4 months vs every 13 months) and review sentiment (100% vs 91%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Kitty Q holds the better App Store score, 4.9 against 2.7. That said, the two scores are not equally well evidenced: Kitty Q has 400 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 91% of Kitty Q's written reviews are positive against 100% of The Unstoppables 2's, so the app with the better star average is not the one people write more warmly about.

Kitty Q ships an update every 13 months, The Unstoppables 2 every 4 months. The most recent releases landed on October 30, 2026 and October 24, 2026 respectively.
