Verdict
The clearest difference is in-app purchases: ForneyField at none against Construction Master Pro Calc's 20. ForneyField also leads on iOS requirement (12.0 vs 15.0). Construction Master Pro Calc's advantage is ratings volume (40K vs 2) and update cadence (every 3 weeks vs every 3 months). On price, ads and device support there is nothing between them.
