Verdict
The clearest difference is price: iDoctus at Free against NephroCalc™'s $3.99. iDoctus also leads on update cadence (weekly vs every 10 months) and ratings volume (38 vs 1). NephroCalc™'s advantage is rating (5.0 vs 4.7) and chart position (#142 vs unranked). On ads, in-app purchases and device support there is nothing between them.
