# Pipe Trades Pro Calc vs Fraction Help

The clearest difference is review sentiment: Fraction Help at 100% against Pipe Trades Pro Calc's 43%. Fraction Help also leads on iOS requirement (10.0 vs 14.0). Pipe Trades Pro Calc's advantage is rating (4.8 vs 4.4) and ratings volume (4.4K vs 208). On price, update cadence, 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 Fraction Help sells 3 one-off in-app purchases. 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 4.4. That said, the two scores are not equally well evidenced: Pipe Trades Pro Calc has 4.4K ratings behind it against 208, so its average is the more settled of the two. Written reviews complicate that: 43% of Pipe Trades Pro Calc's written reviews are positive against 100% of Fraction Help'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 7 months. The most recent releases landed on November 6, 2026 and November 1, 2026 respectively.
