A vs Deflection Pro
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
A
This application simplifies the design of RC beams, offering detailed calculation steps for confidence in results. It initially supports ACI 318 building codes in US and Metric units, with plans to add more design codes.
- Simplified RC beam design
- Detailed calculation steps
- ACI 318 Building Code support
- US and Metric units
- Future design code additions

The A-Beam+ is the extension of the previous A-Beam app that make the design of the RC beam easy and as simple as using the normal calculator. But behind the simplicity the app also provide the very details of the calculation in every step to make you confident with the calculation result. The initial version support for the "ACI 318" Building Code both US & Metric (SI-Metric and MKS-Metric) units with more other design codes will be added.
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
- Save to external file

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: A at $4.99 against Deflection Pro's $19.99. Deflection Pro's advantage is rating (4.7 vs 1.0) and update cadence (every 5 weeks vs every 9 months). On ads, in-app purchases and monetization model 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
A costs $4.99 and Deflection Pro $19.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Deflection Pro holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: Deflection Pro has 16 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 60% of A's written reviews are positive against 69% of Deflection Pro's.
A ships an update every 9 months, Deflection Pro every 5 weeks. The most recent releases landed on October 6, 2026 and October 4, 2026 respectively.
