# Construction Calculator Pro #1 vs Sixteenths

The clearest difference is rating: Construction Calculator Pro #1 at 4.5 against Sixteenths's 3.7. Construction Calculator Pro #1 also leads on in-app purchases (none vs 1) and ratings volume (97 vs 3). Sixteenths's advantage is review sentiment (100% vs 67%) and update cadence (every 4 days vs every 12 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Sixteenths sells 1 one-off in-app purchase. Construction Calculator Pro #1 asks for nothing beyond the download.

Construction Calculator Pro #1 holds the better App Store score, 4.5 against 3.7. That said, the two scores are not equally well evidenced: Construction Calculator Pro #1 has 97 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 67% of Construction Calculator Pro #1'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.

Construction Calculator Pro #1 ships an update every 12 months, Sixteenths every 4 days. Both last shipped on October 24, 2026.
