Anesthesia One is a feature-rich toolbox and assistant for healthcare professionals providing patient-centered anesthesia care. “Mega apps” for anesthesia already exist, with the advantage of bringing multiple tools—calculators, drugs, crisis management, and more—under one umbrella. In everyday practice, though, navigating these large digital references can be a challenge. Unlike many other apps, Anesthesia One lets you custom-arrange tools (risk calculators, crises, drugs, practice guidelines, and more) for quick access in Favorites. When you are not sure which tools you need, enter patient and case details in the Assistant to see relevant risk calculators and guidelines. You can save the risk evaluation and case-relevant guidance as a log and share it with a colleague. Ask AnesthesiaOne is a new way to explore guidance: ask questions in plain language with search across curated anesthesia guidelines and education sources, optionally narrow by source, and open links to original documents when you want to read the full reference. Anesthesia One is designed to work online and offline, so critical management resources stay available when you need them most. We are a small team dedicated to putting helpful anesthesia tools at your fingertips. Our feature set can be updated over the air, and we plan to add more tools and guidelines as they become available. We are always working to improve and welcome your feedback. Thank you for your support.

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
