# Cat IQ Test vs K

The clearest difference is rating: Cat IQ Test at 5.0 against K's 2.1. K's advantage is ratings volume (11 vs 2) and iOS requirement (15.0 vs 17.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Cat IQ Test sells 1 one-off in-app purchase and K sells 4 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Cat IQ Test holds the better App Store score, 5.0 against 2.1. That said, the two scores are not equally well evidenced: K has 11 ratings behind it against 2, so its average is the more settled of the two.

Cat IQ Test ships an update every 2 months, K every 5 weeks. Both last shipped on October 24, 2026.
