Verdict

The call

The clearest difference is price: Construction Master Pro Calc at Free against Torque Unit Converter's $1.99. Construction Master Pro Calc also leads on update cadence (every 3 weeks vs every 14 months) and ratings volume (40K vs 12). Torque Unit Converter's advantage is review sentiment (100% vs 60%) and in-app purchases (none vs 20). On ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Construction Master Pro Calc holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Construction Master Pro Calc has 40K ratings behind it against 12, 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 100% of Torque Unit Converter'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, Torque Unit Converter every 14 months. The most recent releases landed on October 22, 2026 and October 7, 2026 respectively.
