# Calculator + vs Construction Master Pro Calc

The clearest difference is ads: Construction Master Pro Calc at none against Calculator +'s shown. Construction Master Pro Calc also leads on rating (4.8 vs 4.6) and chart position (#41 vs unranked). Calculator +'s advantage is review sentiment (85% vs 60%) and update cadence (every 4 days vs every 3 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Calculator + sells 12 in-app purchases, starting at $4.99 per month and Construction Master Pro Calc sells 12 in-app purchases, starting at $3.69 per month. Whichever you choose, the download price is not the number that matters.

Construction Master Pro Calc holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 10K and 40K respectively. Written reviews complicate that: 85% of Calculator +'s written reviews are positive against 60% of Construction Master Pro Calc's, so the app with the better star average is not the one people write more warmly about.

Calculator + ships an update every 4 days, Construction Master Pro Calc every 3 weeks. The most recent releases landed on September 24, 2026 and September 25, 2026 respectively.
