# Detective Solitaire vs Category Topic

The clearest difference is review sentiment: Detective Solitaire at 50% against Category Topic's 0%. Detective Solitaire also leads on monetization model (ad-supported vs free with in-app purchases). Category Topic's advantage is rating (5.0 vs 4.7). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Detective Solitaire sells 13 one-off in-app purchases and Category Topic sells 13 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Category Topic holds the better App Store score, 5.0 against 4.7. Both are backed by a comparable volume of ratings — 194 and 122 respectively. Written reviews complicate that: 50% of Detective Solitaire's written reviews are positive against 0% of Category Topic's, so the app with the better star average is not the one people write more warmly about.

Detective Solitaire ships an update every 10 days, Category Topic fortnightly. The most recent releases landed on October 19, 2026 and October 20, 2026 respectively.
