Flat Metal Patterns is a metal pattern calculation program that helps us save time making the pattern and avoids possible errors that we may have when drawing the pattern by hand. You can also find products, tools and accessories online for the branch of industrial insulation. This application is aimed at experts, inexperienced and beginners; within the application you can find video tutorials that will guide you through the process of how to use the calculated pattern. For people who are experienced in tracing a pattern by hand, it will help them to avoid mistakes, calculate the pattern in seconds, and thus save time. The pattern calculation program is made based on mathematical calculations and converting those calculations into the pattern that we are used to work with. Inside you can find up to 20 different patterns, as well as Diameter - Circumference calculation, Pipe - Insulation reference tables and a length units calculator. Circumference-Diameter - The application works mainly with circumference values. Additionally, the application accepts diameter values that are converted to circumference. Pipe size - If you have the exact data of a pipe, the application has the ability to determine the exact circumference of the pipe. Smart calculator - Extremely important for specific operations on known fractions and decimals. This means that the calculator accepts the fractions of a conventional tape measure, and returns the results in the same way. Scale - An extremely important feature of the application that makes it easy for us to manufacture large-size patterns in parts. Terms of use: https://flatmetalpatterns.com/terms-and-conditions/

Verdict
The clearest difference is review sentiment: Flat Metal Patterns at 83% against Pipe Trades Pro Calc's 42%. Flat Metal Patterns also leads on update cadence (every 5 weeks vs every 7 months). Pipe Trades Pro Calc's advantage is rating (4.8 vs 4.4) and ratings volume (4.3K vs 25). On price, ads, 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 Metal Patterns sells 3 in-app purchases, starting at $7.99 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 4.4. That said, the two scores are not equally well evidenced: Pipe Trades Pro Calc has 4.3K ratings behind it against 25, 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 83% of Flat Metal Patterns'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, Flat Metal Patterns every 5 weeks. The most recent releases landed on September 26, 2026 and September 16, 2026 respectively.
