User Reviews

Users love Master Anesthesia for its ease of use, comprehensive and clinically relevant information, and practical dosing tools, with CE integration and pediatric dosing support highlighted as strong benefits. Many reviews note its usefulness at the bedside and in rotations, as well as responsive support and helpful updates. However, recurrent reliability problems persist: crashes and white-screen freezes, especially in calculations; login and pro-subscription access issues; intermittent offline/content loading limitations; and some concerns about subscription pricing and value. Overall, the app is highly valuable when working, but reliability and access hurdles remain.

Pros

Easy to use and intuitive interface.
Comprehensive, relevant information that's useful for everyday anesthesia practice.
Effective drug calculation and dosing tools, with strong pediatric dosing support.
Convenient for continuing education (CE) within the app.
Responsive customer support and steady updates that improve functionality.

Cons

Frequent crashes and freezes, especially in the calculator, with white-screen errors on startup.
Pro subscription introduces access issues: prompts to re-purchase, content not loading, and overall reliability concerns.
Login/session problems: required re-login on open and slow/blocked verification.
Offline access and content loading can be inconsistent or unavailable.
Perceived value concerns due to price, subscription model, and double-charging worries.

By far the best companion app for anyone in the anaesthesia field.

I’ve been using MA for at least 5 or so years. It’s a great app and each update is an amazing improvement. I recommend this app to colleagues all the time. It’s easy to navigate and easy to read especially in the OR. Keep up the great work!
