Verdict
The clearest difference is price: Construction Master Pro Calc at Free against Piping DataBase's $9.99. Construction Master Pro Calc also leads on ratings volume (40K vs 212). Piping DataBase's advantage is review sentiment (86% vs 60%) and iOS requirement (6.0 vs 15.0). On rating, update cadence, ads and in-app purchases there is nothing between them.
