# Carpenter Pro Calc vs Construction Calculator

The clearest difference is rating: Carpenter Pro Calc at 5.0 against Construction Calculator's 4.3. Carpenter Pro Calc also leads on update cadence (every 6 days vs every 6 weeks). Construction Calculator's advantage is ratings volume (48 vs 1) and iOS requirement (15.1 vs 18.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Carpenter Pro Calc sells 1 one-off in-app purchase and Construction Calculator sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Carpenter Pro Calc holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Construction Calculator has 48 ratings behind it against 1, so its average is the more settled of the two.

Carpenter Pro Calc ships an update every 6 days, Construction Calculator every 6 weeks. The most recent releases landed on October 31, 2026 and November 5, 2026 respectively.
