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 4 months). Piping DataBase's advantage is in-app purchases (none vs 1) and iOS requirement (8.0 vs 15.1). On ads and device support there is nothing between them.
