Deflection Pro is an advanced structural analysis calculator for beam, truss, and frame design. The software is designed to be simple, intuitive, and useful for structural engineers worldwide. Like our other apps, it is designed to run on all your devices. LOAD COMBINATIONS Deflection Pro generates common load combinations based on American and European standards. Simply select a desired design method in the settings page and assign a category to each load. The results are seamlessly aggregated and integrated into the same charts and interface as if you were designing a simple beam case. BEAM COLUMN CAPACITY CHECKS Deflection Pro calculates beam column strength capacity for flexure, shear, tension, and compression based on the AISC specification. The software accurately reproduces tabulated values in steel construction manuals. Flexure Design • Yielding • Lateral torsional buckling • Local buckling • Flange local buckling • Compression flange local buckling • Web local buckling • Compression tee stem local buckling Shear Design • Web shear strength • Web shear strength, considering field action Tension Design • Yielding tensile strength • Rupture tensile strength Compression Design • Flexural buckling • Torsional buckling OTHER FEATURES Since this is our latest and greatest structural analysis app, we are actively improving it and adding new functionality. It receives more frequent updates than other tiers of our software. Other advanced functionality include the ability to directly export to PDF and to save to an external file for backup and sharing.

Verdict
The clearest difference is price: iRhino 3D at Free against Deflection Pro's $19.99. iRhino 3D also leads on update cadence (fortnightly vs every 5 weeks) and ratings volume (80 vs 16). Deflection Pro's advantage is review sentiment (69% vs 55%) and device support (4 vs 2). On rating, ads and in-app purchases 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
iRhino 3D is free to download; Deflection Pro costs $19.99 up front. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 4.6 for iRhino 3D against 4.7 for Deflection Pro. That said, the two scores are not equally well evidenced: iRhino 3D has 80 ratings behind it against 16, so its average is the more settled of the two. Written reviews are what separate them: 55% of iRhino 3D's written reviews are positive against 69% of Deflection Pro's.
iRhino 3D ships an update fortnightly, Deflection Pro every 5 weeks. The most recent releases landed on September 20, 2026 and September 17, 2026 respectively.
