# Block Out! vs Stack Sort

The clearest difference is ratings volume: Block Out! at 337K against Stack Sort's 7.7K. Block Out! also leads on review sentiment (47% vs 31%) and chart position (#2 vs unranked). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Block Out! sells 11 one-off in-app purchases and Stack Sort sells 14 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Block Out! against 4.7 for Stack Sort. That said, the two scores are not equally well evidenced: Block Out! has 337K ratings behind it against 7.7K, so its average is the more settled of the two. Written reviews are what separate them: 47% of Block Out!'s written reviews are positive against 31% of Stack Sort's.

Block Out! ships an update weekly, Stack Sort every 10 days. Both last shipped on October 29, 2026.
