# Core Anesthesia vs Anisthesia

The clearest difference is ratings volume: Core Anesthesia at 537 against Anisthesia's 10. Core Anesthesia also leads on chart position (#196 vs unranked). Anisthesia's advantage is review sentiment (100% vs 90%) and device support (3 vs 1). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Core Anesthesia sells 14 in-app purchases, starting at $9.99 per month and Anisthesia sells 1 in-app purchase, starting at $64.99 per year. 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 Core Anesthesia against 4.8 for Anisthesia. That said, the two scores are not equally well evidenced: Core Anesthesia has 537 ratings behind it against 10, so its average is the more settled of the two. Written reviews are what separate them: 90% of Core Anesthesia's written reviews are positive against 100% of Anisthesia's.

Core Anesthesia ships an update every 3 weeks, Anisthesia every 2 weeks. Both last shipped on October 24, 2026.
