Verdict

The call

Calculator + and Pipe Trades Pro Calc both sit at 4.6 stars, but that hides the real split: 85% of Calculator +'s written reviews are positive against 43% of Pipe Trades Pro Calc's. Calculator + also leads on update cadence (every 5 days vs every 7 months). Pipe Trades Pro Calc's advantage is ads (none vs shown) and chart position (#186 vs unranked). On price, rating, ratings volume and in-app purchases there is nothing between them.
