# Construction Master Pro Calc vs Sixteenths

The clearest difference is rating: Construction Master Pro Calc at 4.8 against Sixteenths's 3.7. Construction Master Pro Calc also leads on ratings volume (40K vs 3) and chart position (#49 vs unranked). Sixteenths's advantage is review sentiment (100% vs 60%) and update cadence (every 4 days vs every 3 weeks). On price, ads, in-app purchases and monetization model 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 Sixteenths sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Construction Master Pro Calc holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: Construction Master Pro Calc has 40K ratings behind it against 3, 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 Sixteenths's, so the app with the better star average is not the one people write more warmly about.

Construction Master Pro Calc ships an update every 3 weeks, Sixteenths every 4 days. The most recent releases landed on October 21, 2026 and October 19, 2026 respectively.
