ReceptionRating · Positive reviews · Number of ratings

Master Anesthesia holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Master Anesthesia has 2K ratings behind it against 177, so its average is the more settled of the two. Written reviews complicate that: 85% of Vargo Anesthesia Mega App's written reviews are positive against 79% of Master Anesthesia's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Vargo Anesthesia Mega App ships an update every 2 weeks, Master Anesthesia every 6 days. The most recent releases landed on September 23, 2026 and September 22, 2026 respectively.
