# Stack Up vs Stack Colors!

The clearest difference is review sentiment: Stack Up at 100% against Stack Colors!'s 49%. Stack Up also leads on ads (none vs shown) and iOS requirement (9.0 vs 14.0). Stack Colors!'s advantage is ratings volume (181K vs 129) and rating (4.6 vs 4.4). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Stack Up sells 1 one-off in-app purchase and Stack Colors! sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Stack Colors! holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Stack Colors! has 181K ratings behind it against 129, so its average is the more settled of the two. Written reviews complicate that: 100% of Stack Up's written reviews are positive against 49% of Stack Colors!'s, so the app with the better star average is not the one people write more warmly about.

Stack Up ships an update every 2 months, Stack Colors! every 6 weeks. The most recent releases landed on October 26, 2026 and October 30, 2026 respectively.
