# SitePlan vs Construction Calculator A1

The clearest difference is rating: Construction Calculator A1 at 4.8 against SitePlan's 1.0. Construction Calculator A1 also leads on ratings volume (26 vs 1) and device support (4 vs 2). SitePlan's advantage is ads (none vs shown) and review sentiment (86% vs 67%). On price, update cadence and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Construction Calculator A1 holds the better App Store score, 4.8 against 1.0. That said, the two scores are not equally well evidenced: Construction Calculator A1 has 26 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 86% of SitePlan's written reviews are positive against 67% of Construction Calculator A1's, so the app with the better star average is not the one people write more warmly about.

SitePlan ships an update fortnightly, Construction Calculator A1 every 4 weeks. The most recent releases landed on October 8, 2026 and October 15, 2026 respectively.
