# Anesthesia One vs Anesthetize

The clearest difference is update cadence: Anesthetize at monthly against Anesthesia One's every 4 months. Anesthesia One's advantage is ratings volume (6 vs 1) and iOS requirement (15.1 vs 17.0). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Anesthesia One sells 2 in-app purchases, starting at $0.99 per month 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.

Anesthetize holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Anesthesia One has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Anesthesia One ships an update every 4 months, Anesthetize monthly. The most recent releases landed on October 24, 2026 and October 23, 2026 respectively.
