Verdict
The clearest difference is price: HydroCalc Basic at Free against Piping DataBase's $3.99. HydroCalc Basic also leads on update cadence (every 11 days vs every 3 months). Piping DataBase's advantage is chart position (#184 vs unranked) and iOS requirement (8.0 vs 15.1). On ads, in-app purchases and device support there is nothing between them.
