Verdict

The call

The clearest difference is rating: Construction Master Pro Calc at 4.8 against Construction Calculator Master's 4.3. Construction Master Pro Calc also leads on ratings volume (40K vs 436) and chart position (#41 vs unranked). Construction Calculator Master's advantage is review sentiment (70% vs 60%) and iOS requirement (11.0 vs 15.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Construction Master Pro Calc sells 12 in-app purchases, starting at $3.69 per month and Construction Calculator Master sells 10 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Construction Master Pro Calc holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: Construction Master Pro Calc has 40K ratings behind it against 436, 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 70% of Construction Calculator Master'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 Master fortnightly. The most recent releases landed on September 25, 2026 and September 22, 2026 respectively.
