# Criminal Case vs Diamond Quest

The clearest difference is update cadence: Diamond Quest at weekly against Criminal Case's every 3 months. Diamond Quest also leads on review sentiment (71% vs 60%) and iOS requirement (12.0 vs 15.6). Criminal Case's advantage is ratings volume (36K vs 641) and rating (4.7 vs 4.5). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Criminal Case sells 10 in-app purchases, starting at $2.99 per 7 days and Diamond Quest sells 15 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Criminal Case holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Criminal Case has 36K ratings behind it against 641, so its average is the more settled of the two. Written reviews complicate that: 60% of Criminal Case's written reviews are positive against 71% of Diamond Quest's, so the app with the better star average is not the one people write more warmly about.

Criminal Case ships an update every 3 months, Diamond Quest weekly. Both last shipped on October 19, 2026.
