# Opus vs Casta

The clearest difference is ratings volume: Opus at 35 against Casta's 3. Casta's advantage is update cadence (fortnightly vs monthly) and device support (3 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

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

On the App Store both sit at effectively the same score — 4.6 for Opus against 4.7 for Casta. That said, the two scores are not equally well evidenced: Opus has 35 ratings behind it against 3, so its average is the more settled of the two.

Opus ships an update monthly, Casta fortnightly. The most recent releases landed on October 6, 2026 and September 29, 2026 respectively.
