# Stack Number vs Block Merge

The clearest difference is rating: Block Merge at 4.7 against Stack Number's 4.0. Block Merge also leads on update cadence (monthly vs every 24 months) and ratings volume (43 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Block Merge holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Block Merge has 43 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Stack Number's written reviews are positive against 97% of Block Merge's, so the app with the better star average is not the one people write more warmly about.

Stack Number ships an update every 24 months, Block Merge monthly. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
