With version 10, the application allows you to quickly visualize relational values related to pipes and elbows (Carbon Steel / Stainless Steel) according to ISO / ASME standards, making it a practical tool for industrial piping. An ultra-fast and intuitive way to retrieve: Diameter → Angle → Radius → Extrados → Intrados, regardless of the angle or diameter, in a single step. This provides up to 810 possible entries with one click. With this version, you can choose how to control diameter selection: via a slider, or via pre-filled input fields. ElbowData is free forever. Features Elbow formats: 2D / 3D / 5D Segmented elbows (lobster back): 8 generators / 12 generators / 16 generators PDF abacuses and isometric sheets including: bill of materials based on the selected language, technical memo, generator templates Inch / millimeter conversion Scientific calculator optimized for industrial piping Saved language selection This version benefits from UI, design, and ergonomic optimizations. Advertisements are now non-intrusive, ensuring a smooth and free user experience, with rewarded ads and technical articles related to industrial piping. You can support the developer with your suggestions and/or access the premium version. Thank you! If you have any feedback about the application, feel free to contact me by email.

Verdict
The clearest difference is rating: Flat Pattern Bend Calculator at 4.6 against ElbowData's 3.0. Flat Pattern Bend Calculator also leads on ratings volume (151 vs 2). ElbowData's advantage is review sentiment (75% vs 45%) and monetization model (ad-supported vs free with in-app purchases). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Flat Pattern Bend Calculator sells 6 in-app purchases, starting at $4.99 per 7 days and ElbowData sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Flat Pattern Bend Calculator holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: Flat Pattern Bend Calculator has 151 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 45% of Flat Pattern Bend Calculator's written reviews are positive against 75% of ElbowData'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 2 months. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
