Verdict

The call

The clearest difference is in-app purchases: Construction Calculator Pro #1 at none against Construction Master Pro Calc's 20. Construction Master Pro Calc's advantage is update cadence (every 3 weeks vs every 12 months) and ratings volume (40K vs 96). On price, review sentiment and ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Construction Master Pro Calc holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Construction Master Pro Calc has 40K ratings behind it against 96, so its average is the more settled of the two. Written reviews complicate that: 60% of Construction Master Pro Calc's written reviews are positive against 67% of Construction Calculator Pro #1's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Construction Master Pro Calc ships an update every 3 weeks, Construction Calculator Pro #1 every 12 months. The most recent releases landed on October 17, 2026 and September 27, 2026 respectively.
