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 rating: Flat Pattern & Bend Calculator at 5.0 against Flat Metal Patterns's 4.4. Flat Metal Patterns's advantage is update cadence (every 5 weeks vs every 4 months) and ratings volume (25 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Flat Metal Patterns sells 3 in-app purchases, starting at $7.99 per month and Flat Pattern & Bend Calculator sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Flat Pattern & Bend Calculator holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Flat Metal Patterns has 25 ratings behind it against 2, so its average is the more settled of the two.
Flat Metal Patterns ships an update every 5 weeks, Flat Pattern & Bend Calculator every 4 months. The most recent releases landed on September 16, 2026 and September 7, 2026 respectively.
