# inchCALC+ vs Construction Calculator

The clearest difference is price: Construction Calculator at Free against inchCALC+'s $4.99. Construction Calculator also leads on rating (4.7 vs 3.7) and update cadence (every 6 days vs every 2 months). inchCALC+'s advantage is in-app purchases (none vs 9) and review sentiment (74% vs 54%). On ads and device support there is nothing between them.

Construction Calculator is free to download; inchCALC+ costs $4.99 up front. Construction Calculator sells 8 in-app purchases, starting at $4.99 per month. inchCALC+ asks for nothing beyond the download.

Construction Calculator holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: Construction Calculator has 625 ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 74% of inchCALC+'s written reviews are positive against 54% of Construction Calculator's, so the app with the better star average is not the one people write more warmly about.

inchCALC+ ships an update every 2 months, Construction Calculator every 6 days. Both last shipped on October 16, 2026.
