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 CONTACT We like to hear from you!

About

Beam HPC

This app calculates structural diagrams for beams, including moment, shear, and deflection. It supports various loads, supports, and material properties, allowing for interactive adjustments and comparisons. Designed for educational purposes, it helps users visualize and understand beam behavior.

Highlights
  • Moment, shear, and deflection diagrams
  • Multiple load types (forces, moments, distributed)
  • Adjustable support conditions (pinned, fixed, roller)
  • Segmented beams with varying properties
  • Interactive drag-and-drop interface
  • Educational focus on beam behavior
Features
Read full description

Beam HPC app calculates the moment, shear, deflection and rotation diagrams for a beam with various types of loading. Loading types include forces, moments and distributed loads. The load location and magnitude can be changed at any time. There are three types of supports (i.e. boundary conditions) including pinned, fixed and vertical roller. Each beam can be split into sub-beam segments. Each beam segment can have a different moment of inertia (I) and stiffness (E). The user can click and drag all items to quickly change and compare results. This program is designed for educational uses only. It should not be used for commercial purposes. There is no warranty or guarantee the results are accurate, and the user accepts all responsibility for values calculated.

Verdict

The call

The clearest difference is price: Beam HPC at Free against Deflection's $4.99. Beam HPC also leads on review sentiment (100% vs 74%) and iOS requirement (9.0 vs 15.0). Deflection's advantage is rating (4.6 vs 4.0) and update cadence (every 6 weeks vs every 18 months). On ads, in-app purchases and device support there is nothing between them.

Beam HPC is free to download; Deflection costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

Deflection holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Deflection has 115 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 74% of Deflection's written reviews are positive against 100% of Beam HPC's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Deflection ships an update every 6 weeks, Beam HPC every 18 months. The most recent releases landed on October 22, 2026 and October 2, 2026 respectively.
