Verdict
The clearest difference is rating: NefroCalc at 5.0 against MediCalc®'s 4.5. NefroCalc also leads on review sentiment (100% vs 81%) and iOS requirement (8.0 vs 13.0). MediCalc®'s advantage is ratings volume (21 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.
