Verdict

The call

The clearest difference is review sentiment: Sixteenths at 100% against Construction Calculator's 54%. Construction Calculator's advantage is rating (4.7 vs 3.7) and ratings volume (672 vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Construction Calculator holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: Construction Calculator has 672 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 54% of Construction Calculator's written reviews are positive against 100% of Sixteenths's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Construction Calculator ships an update every 5 days, Sixteenths every 4 days. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
