Verdict
Flap Happy and Stack Jump both sit at 4.4 stars, but that hides the real split: 85% of Flap Happy's written reviews are positive against 48% of Stack Jump's. Flap Happy also leads on ads (none vs shown) and iOS requirement (8.0 vs 13.0). Stack Jump's advantage is update cadence (every 4 weeks vs every 28 months) and ratings volume (299K vs 19). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Flap Happy 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 19, so its average is the more settled of the two. Written reviews complicate that: 85% of Flap Happy'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.
Flap Happy ships an update every 28 months, Stack Jump every 4 weeks. The most recent releases landed on August 18, 2026 and October 1, 2026 respectively.
