Verdict

The call

The clearest difference is ads: Pipe Trades Pro Calc at none against Flat Pattern Bend Calculator's shown. Pipe Trades Pro Calc also leads on ratings volume (4.3K vs 151) and rating (4.8 vs 4.6). Flat Pattern Bend Calculator's advantage is update cadence (every 2 months vs every 7 months). On price, review sentiment, in-app purchases and monetization model 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 Flat Pattern Bend Calculator sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Pipe Trades Pro Calc holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Pipe Trades Pro Calc has 4.3K ratings behind it against 151, 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 45% of Flat Pattern Bend Calculator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Pipe Trades Pro Calc ships an update every 7 months, Flat Pattern Bend Calculator every 2 months. Both last shipped on September 24, 2026.
