# Calculator + vs Pipe Trades Pro Calc

Calculator + and Pipe Trades Pro Calc both sit at 4.6 stars, but that hides the real split: 85% of Calculator +'s written reviews are positive against 43% of Pipe Trades Pro Calc's. Calculator + also leads on update cadence (every 5 days vs every 7 months). Pipe Trades Pro Calc's advantage is ads (none vs shown) and chart position (#191 vs unranked). On price, rating, ratings volume and in-app purchases there is nothing between them.

Both are free to download. Calculator + sells 12 in-app purchases, starting at $4.99 per month and Pipe Trades Pro Calc sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Pipe Trades Pro Calc holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 10K and 4.4K respectively. Written reviews complicate that: 85% of Calculator +'s written reviews are positive against 43% of Pipe Trades 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 5 days, Pipe Trades Pro Calc every 7 months. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
