# Calculator Construction Pro vs Construction Expert A1 PRO

Calculator Construction Pro and Construction Expert A1 PRO both sit at 5.0 stars, but that hides the real split: 100% of Construction Expert A1 PRO's written reviews are positive against 50% of Calculator Construction Pro's. Construction Expert A1 PRO also leads on device support (4 vs 2) and iOS requirement (15.0 vs 17.0). Calculator Construction Pro's advantage is in-app purchases (none vs 3) and update cadence (every 3 days vs fortnightly). On price, rating, ratings volume and ads there is nothing between them.

Both are free to download. Construction Expert A1 PRO sells 3 in-app purchases, starting at $2.99 per month. Calculator Construction Pro asks for nothing beyond the download.

Calculator Construction Pro holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 4 and 6 respectively. Written reviews complicate that: 50% of Calculator Construction Pro's written reviews are positive against 100% of Construction Expert A1 PRO's, so the app with the better star average is not the one people write more warmly about.

Calculator Construction Pro ships an update every 3 days, Construction Expert A1 PRO fortnightly. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
