Verdict
Pipe Trades Pro Calc and WeldKit both sit at 4.8 stars, but that hides the real split: 100% of WeldKit's written reviews are positive against 43% of Pipe Trades Pro Calc's. WeldKit also leads on update cadence (every 3 weeks vs every 7 months). Pipe Trades Pro Calc's advantage is ads (none vs shown) and ratings volume (4.4K vs 1). On price, rating, in-app purchases and monetization model there is nothing between them.
