# Construction Calc Pro Lite vs PowerOne calculator

Construction Calc Pro Lite and PowerOne calculator both sit at 4.8 stars, but that hides the real split: 50% of PowerOne calculator's written reviews are positive against 10% of Construction Calc Pro Lite's. PowerOne calculator also leads on ads (none vs shown) and ratings volume (806 vs 5). Construction Calc Pro Lite's advantage is in-app purchases (none vs 2). On price, rating, update cadence and device support there is nothing between them.

Both are free to download. PowerOne calculator sells 2 in-app purchases, starting at $2.99 per month. Construction Calc Pro Lite asks for nothing beyond the download.

Construction Calc Pro Lite holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: PowerOne calculator has 806 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 10% of Construction Calc Pro Lite's written reviews are positive against 50% of PowerOne calculator's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on November 1, 2026 and November 2, 2026 respectively.
