# Sort Stack vs Color Sort 3D

The clearest difference is ads: Sort Stack at none against Color Sort 3D's shown. Sort Stack also leads on iOS requirement (10.0 vs 13.0). Color Sort 3D's advantage is rating (4.8 vs 4.5) and update cadence (fortnightly vs monthly). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Sort Stack sells 6 one-off in-app purchases and Color Sort 3D sells 3 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Color Sort 3D holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Color Sort 3D has 2.8K ratings behind it against 516, so its average is the more settled of the two. Written reviews complicate that: 75% of Sort Stack's written reviews are positive against 68% of Color Sort 3D's, so the app with the better star average is not the one people write more warmly about.

Sort Stack ships an update monthly, Color Sort 3D fortnightly. The most recent releases landed on October 16, 2026 and October 18, 2026 respectively.
