# Decalcomanie Gallery vs Unsolved Case Files 3D

The clearest difference is ratings volume: Decalcomanie Gallery at 4.2K against Unsolved Case Files 3D's 13. Decalcomanie Gallery also leads on rating (4.6 vs 4.4) and iOS requirement (10.0 vs 12.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Decalcomanie Gallery sells 1 one-off in-app purchase and Unsolved Case Files 3D sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Decalcomanie Gallery holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Decalcomanie Gallery has 4.2K ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 64% of Decalcomanie Gallery's written reviews are positive against 67% of Unsolved Case Files 3D's, so the app with the better star average is not the one people write more warmly about.

Decalcomanie Gallery ships an update weekly, Unsolved Case Files 3D every 2 weeks. The most recent releases landed on September 24, 2026 and August 11, 2026 respectively.
