# Sliding Block vs Ouroboros

The clearest difference is rating: Ouroboros at 4.6 against Sliding Block's 1.0. Ouroboros also leads on update cadence (every 5 months vs every 13 months) and ratings volume (10 vs 1). Sliding Block's advantage is review sentiment (100% vs 85%). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Ouroboros holds the better App Store score, 4.6 against 1.0. That said, the two scores are not equally well evidenced: Ouroboros has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Sliding Block's written reviews are positive against 85% of Ouroboros's, so the app with the better star average is not the one people write more warmly about.

Sliding Block ships an update every 13 months, Ouroboros every 5 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
