Verdict
The clearest difference is monetization model: Anesthetize at free with in-app purchases against Master Anesthesia's subscription. Anesthetize also leads on review sentiment (100% vs 78%). Master Anesthesia's advantage is ratings volume (2K vs 1) and update cadence (weekly vs monthly). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Master Anesthesia sells 7 in-app purchases, starting at $69.99 per year and Anesthetize sells 2 in-app purchases, starting at $25.99 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 Master Anesthesia against 5.0 for Anesthetize. That said, the two scores are not equally well evidenced: Master Anesthesia has 2K ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 78% of Master Anesthesia's written reviews are positive against 100% of Anesthetize's.
Master Anesthesia ships an update weekly, Anesthetize monthly. The most recent releases landed on October 25, 2026 and October 23, 2026 respectively.
