Verdict
The clearest difference is review sentiment: Heating & Cooling HVAC Pro+ at 100% against Caleffi Pipe Sizer's 50%. Heating & Cooling HVAC Pro+ also leads on update cadence (every 6 weeks vs every 7 months) and ratings volume (45 vs 1). Caleffi Pipe Sizer's advantage is rating (5.0 vs 4.8) and monetization model (free vs ad-supported). On price, ads, in-app purchases and device support there is nothing between them.

Caleffi Pipe Sizer holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Heating & Cooling HVAC Pro+ has 45 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Caleffi Pipe Sizer's written reviews are positive against 100% of Heating & Cooling HVAC Pro+'s, so the app with the better star average is not the one people write more warmly about.
