# Pipe Trades Pro Calc vs Piping Engineering Toolbox

The clearest difference is rating: Pipe Trades Pro Calc at 4.8 against Piping Engineering Toolbox's 3.7. Pipe Trades Pro Calc also leads on ratings volume (4.3K vs 9) and chart position (#196 vs unranked). Piping Engineering Toolbox's advantage is update cadence (every 3 months vs every 7 months) and iOS requirement (12.0 vs 14.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Pipe Trades Pro Calc sells 2 in-app purchases, starting at $4.99 per month and Piping Engineering Toolbox sells 4 in-app purchases, starting at $1.99 per 7 days. 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 3.7. That said, the two scores are not equally well evidenced: Pipe Trades Pro Calc has 4.3K ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 42% of Pipe Trades Pro Calc's written reviews are positive against 50% of Piping Engineering Toolbox's, so the app with the better star average is not the one people write more warmly about.

Pipe Trades Pro Calc ships an update every 7 months, Piping Engineering Toolbox every 3 months. The most recent releases landed on September 24, 2026 and August 26, 2026 respectively.
