📝 About this app
Deflection is a powerful, versatile calculator for beams, 2D trusses, and 2D frames. The interface is simple and intuitive, and the graphical output is state-of-the-art. In addition to reaction, shear, bending moment, and deflection results, Deflection also computes internal shear and bending stress along the cross section and along the beam.
2D FRAME AND TRUSS EDITOR
The 2D editor is seamlessly integrated with the beam editor. Draw arbitrary frame and truss structures and apply loads and constraints using the same simple interface as for beams. You can visualize results directly within the 2D editor, or you can select a beam and get additional insights.
INTERNAL STRESSES
Obtain internal bending and shear stress diagrams in addition to shear, bending, and deflection diagrams. The internal stresses can be visualized along the length of the beam as well as along the vertical axis of the cross section using the beam editor.
CROSS SECTION EDITOR
Edit built-in cross sections. Moment of inertia and area values are automatically calculated and applied to the rest of the beam calculations.
MORE FEATURES
• The built-in database contains more data for your reference and convenience.
• Apply beam self-weight optionally
• Unlimited design files
• Quick-start templates

🆕 What's New · v11.0.0
Introducing frame and building benchmark examples and extensive improvements throughout the app!
• NEW: Examples gallery in the home screen, including new examples for frames and buildings. Click on the button with a book icon to open it.
• NEW: The new eyedropper button in the frame editor allows you to copy the material and cross-section from one beam to another. To use it, select a beam, press the eyedropper button, and then select another beam to copy from.
• FIXED: Cross section stress analysis for angles and zees is now performed along their principal axes rather than geometric axes.
• IMPROVED: Numerous performance, stability, layout, and interaction enhancements in the 2D editor, especially when working with large models.

★★★★★ So Far So Good!
Just downloaded this and started playing around with it. Quite amazing how the graphics work. Nice that you can specify a structural steel beam shape.…
★★★★★ Nice app
Very good…

★☆☆☆☆ Poor user interface does not hold settings.
Just using this app is a challenge.
When I used ft-lb-in settings they always reverted to metric which was very frustrating.
You have to know everything in the calculations before starting. There is no table of properties for materials or…
★★☆☆☆ Structural Review and Shortcomings
Love the app, great visual interface...but why not 50 and 65 KSI steel?
Today almost all structural steel is grade 50 KSI....this application is now limited to 36 KSI steel design. To make application useful it needs that upgrade.…

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
