Verdict
The clearest difference is in-app purchases: Gleesfun Pro at none against Construction Master Pro Calc's 20. Gleesfun Pro also leads on rating (5.0 vs 4.8) and iOS requirement (13.0 vs 15.0). Construction Master Pro Calc's advantage is ratings volume (40K vs 1) and update cadence (every 3 weeks vs every 3 months). On price, ads and device support there is nothing between them.
