# NephroCalc™ vs Access

The clearest difference is price: Access at Free against NephroCalc™'s $3.99. Access also leads on update cadence (monthly vs every 10 months) and ratings volume (134 vs 1). NephroCalc™'s advantage is rating (5.0 vs 4.2) and iOS requirement (13.0 vs 26). On ads, in-app purchases and device support there is nothing between them.

Access is free to download; NephroCalc™ costs $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.

NephroCalc™ holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Access has 134 ratings behind it against 1, so its average is the more settled of the two.

NephroCalc™ ships an update every 10 months, Access monthly. Both last shipped on October 24, 2026.
