# Yarn! A Jumping Physics Game vs Stack Jump

Yarn! A Jumping Physics Game and Stack Jump both sit at 4.4 stars, but that hides the real split: 88% of Yarn! A Jumping Physics Game's written reviews are positive against 48% of Stack Jump's. Stack Jump's advantage is ratings volume (299K vs 8). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Yarn! A Jumping Physics Game sells 4 one-off in-app purchases and Stack Jump sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Stack Jump holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Stack Jump has 299K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 88% of Yarn! A Jumping Physics Game's written reviews are positive against 48% of Stack Jump's, so the app with the better star average is not the one people write more warmly about.

Yarn! A Jumping Physics Game ships an update monthly, Stack Jump every 4 weeks. The most recent releases landed on September 18, 2026 and September 27, 2026 respectively.
