# Construction Master Pro Calc vs Chalk

The clearest difference is ratings volume: Construction Master Pro Calc at 40K against Chalk's 2. Construction Master Pro Calc also leads on update cadence (every 3 weeks vs every 3 months) and chart position (#44 vs unranked). Chalk's advantage is rating (5.0 vs 4.8). 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 Chalk sells 2 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Chalk holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Construction Master Pro Calc has 40K ratings behind it against 2, so its average is the more settled of the two.

Construction Master Pro Calc ships an update every 3 weeks, Chalk every 3 months. The most recent releases landed on October 19, 2026 and October 16, 2026 respectively.
