# Cube Stack vs Eureka

The clearest difference is review sentiment: Eureka at 77% against Cube Stack's 50%. Eureka also leads on ratings volume (510 vs 4) and rating (4.7 vs 4.5). Cube Stack's advantage is update cadence (every 2 weeks vs every 4 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Cube Stack sells 4 one-off in-app purchases and Eureka sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Eureka holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Eureka has 510 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 50% of Cube Stack's written reviews are positive against 77% of Eureka's.

Cube Stack ships an update every 2 weeks, Eureka every 4 weeks. The most recent releases landed on August 22, 2026 and September 19, 2026 respectively.
