# The Stack System vs Ubeus

The clearest difference is ratings volume: The Stack System at 7K against Ubeus's 6. The Stack System also leads on chart position (#199 vs unranked). Ubeus's advantage is update cadence (every 9 days vs monthly) and review sentiment (100% vs 87%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. The Stack System sells 6 in-app purchases, starting at $9.99 per 7 days and Ubeus sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for The Stack System against 5.0 for Ubeus. That said, the two scores are not equally well evidenced: The Stack System has 7K ratings behind it against 6, so its average is the more settled of the two. Written reviews are what separate them: 87% of The Stack System's written reviews are positive against 100% of Ubeus's.

The Stack System ships an update monthly, Ubeus every 9 days. The most recent releases landed on September 27, 2026 and September 12, 2026 respectively.
