Verdict

The call

The clearest difference is in-app purchases: Anesthesiologists at none against Master Anesthesia's 7. Anesthesiologists also leads on review sentiment (100% vs 79%) and iOS requirement (13.0 vs 15.1). Master Anesthesia's advantage is update cadence (every 6 days vs every 17 months) and ratings volume (2K vs 5). On price, rating, ads and device support there is nothing between them.
