Verdict

The call

The clearest difference is review sentiment: The Chippy Calc at 100% against Construction Calculator's 54%. Construction Calculator's advantage is update cadence (every 6 days vs every 2 months) and ratings volume (625 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Construction Calculator holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Construction Calculator has 625 ratings behind it against 2, 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 The Chippy Calc'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 6 days, The Chippy Calc every 2 months. The most recent releases landed on September 23, 2026 and September 22, 2026 respectively.
