# Master Anesthesia vs GlottaVue Anesthesia

The clearest difference is monetization model: GlottaVue Anesthesia at free against Master Anesthesia's subscription. GlottaVue Anesthesia also leads on review sentiment (100% vs 78%). Master Anesthesia's advantage is ratings volume (2K vs 3) and chart position (#170 vs unranked). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Master Anesthesia sells 7 in-app purchases, starting at $69.99 per year and GlottaVue Anesthesia sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Master Anesthesia against 5.0 for GlottaVue Anesthesia. That said, the two scores are not equally well evidenced: Master Anesthesia has 2K ratings behind it against 3, 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 GlottaVue Anesthesia's.
