# Category Therapy vs Keyword Understanding

The clearest difference is review sentiment: Category Therapy at 100% against Keyword Understanding's 25%. Category Therapy also leads on ratings volume (500 vs 3) and iOS requirement (9.0 vs 15.0). Keyword Understanding's advantage is price ($17.99 vs $29.99) and rating (5.0 vs 4.8). On update cadence, ads, in-app purchases and device support there is nothing between them.

Category Therapy costs $29.99 and Keyword Understanding $17.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Keyword Understanding holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Category Therapy has 500 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of Category Therapy's written reviews are positive against 25% of Keyword Understanding's, so the app with the better star average is not the one people write more warmly about.

Category Therapy ships an update every 8 months, Keyword Understanding every 10 months. The most recent releases landed on October 9, 2026 and October 8, 2026 respectively.
