# Cat Evolution vs Spinner Evolution

The clearest difference is ratings volume: Cat Evolution at 8.1K against Spinner Evolution's 132. Cat Evolution also leads on rating (4.8 vs 4.5). Spinner Evolution's advantage is iOS requirement (11.0 vs 15.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Cat Evolution sells 11 one-off in-app purchases and Spinner Evolution sells 7 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Cat Evolution holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Cat Evolution has 8.1K ratings behind it against 132, so its average is the more settled of the two. Written reviews complicate that: 82% of Cat Evolution's written reviews are positive against 83% of Spinner Evolution's, so the app with the better star average is not the one people write more warmly about.

Cat Evolution ships an update every 10 days, Spinner Evolution every 2 weeks. The most recent releases landed on September 24, 2026 and September 10, 2026 respectively.
