Verdict
The clearest difference is price: Sanford Guide Antimicrobial at Free against NephroCalc™'s $3.99. Sanford Guide Antimicrobial also leads on update cadence (every 2 weeks vs every 10 months) and ratings volume (1.9K vs 1). NephroCalc™'s advantage is in-app purchases (none vs 3) and rating (5.0 vs 4.8). On ads and device support there is nothing between them.
