Verdict
The clearest difference is price: Diagnosaurus® DDx at Free against Pharma AI's $0.99. Diagnosaurus® DDx also leads on rating (4.8 vs 3.4) and ratings volume (2.5K vs 5). Pharma AI's advantage is update cadence (every 6 weeks vs every 10 months). On ads, in-app purchases, monetization model and device support there is nothing between them.
