Deflection Pro vs Auto RC
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Deflection Pro
This advanced structural analysis calculator assists engineers with beam, truss, and frame design. It generates load combinations based on American and European standards and performs detailed beam column capacity checks. Results are presented intuitively, with options to export to PDF and save files.
- Beam, truss, and frame analysis
- Load combination generation (US & EU standards)
- Beam column capacity checks (flexure, shear, tension, compression)
- Detailed design checks for various buckling types
- PDF export

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: Auto RC at Free against Deflection Pro's $19.99. Deflection Pro's advantage is in-app purchases (none vs 8) and rating (4.7 vs 4.5). On review sentiment, ratings volume, update cadence and ads there is nothing between them.

Auto RC is free to download; Deflection Pro costs $19.99 up front. Auto RC sells 8 in-app purchases, starting at $9.99 per month. Deflection Pro asks for nothing beyond the download.
Deflection Pro holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 16 and 6 respectively. Written reviews complicate that: 69% of Deflection Pro's written reviews are positive against 75% of Auto RC's, so the app with the better star average is not the one people write more warmly about.
Deflection Pro ships an update every 5 weeks, Auto RC every 3 weeks. The most recent releases landed on September 17, 2026 and August 31, 2026 respectively.
