# Master Anesthesia vs Emergency Manual

The clearest difference is in-app purchases: Emergency Manual at none against Master Anesthesia's 7. Emergency Manual also leads on review sentiment (100% vs 78%). Master Anesthesia's advantage is ratings volume (2K vs 12) and chart position (#144 vs unranked). On price, rating, ads and device support there is nothing between them.

Both are free to download. Master Anesthesia sells 7 in-app purchases, starting at $69.99 per year. Emergency Manual asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Master Anesthesia against 5.0 for Emergency Manual. That said, the two scores are not equally well evidenced: Master Anesthesia has 2K ratings behind it against 12, 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 Emergency Manual's.
