What's New in Deflection Pro

12.1.0

June 16, 2025

• IMPROVED: Significant improvements in calculation speed and CPU/memory management when working with large models and large numbers of load combinations. • NEW: Open *.deflection files directly from the Files app (recommended). • NEW: Multitasking window support. Open separate windows to work on multiple files at a time. • FIXED: You can now open our files from certain 3rd party file sharing apps. • NEW: Canadian load combinations. • FIXED: Transient calculation glitch caused by deleting nodes in the 2d editor. • FIXED: Error in deflection curves under certain situations when Timoshenko was enabled. • FIXED: App crash due to very large models, particularly in smaller devices. • FIXED: Error in EU load combinations triggered when multiple live loads with a load factor of 1 were present.

Amazing App for Structural Analysis

I was looking for something that could do complicated trusses that didn’t cost an arm and a leg and came across this one!
I have verified the results with multiple text book examples and every one is within the rounding error of the textbook!
Excellent layout and really easy to use, very little learning curve as it is very intuitive!
The only reason I didn’t give 5 start is because I would really like to see the load results broken down into the different load types as when I carry the loads down in woodworks or another design program I need to input unfactored loads, my only complaint!
Keep up the good work guys!

Missing units

Dear developer.

I'd like to express my gratitude for this straightforward and valuable app. I'd like to bring to your attention that in Europe, the standard unit for stress is (N/mm^2), which currently isn't available in the app's settings. Would it be possible to include this unit in the list of stress units?

Once more, thank you for your hard work and dedication.

Response from developer

This means a lot, and we really appreciate it. Although we already have MPa, which equals 1 N/mm^2, we've added N/mm^2 as part of the upcoming 8.0.0 release.

Migrate models?

I’ll return and increase the rating if I learn from the developer how to see my models from the regular version.

2nd review important problem

This app does not consider lateral support of the beam compression flange. This is a serious omission if used by someone that is not knowledgeable with beam design such as architects, construction people, engineering students, etc.
At least one app in the App Store does take this in consideration and that is the “Steel Beams” app. However it does not have all the bells an whistles of Deflection Pro.

Response from developer

Thank you for pointing out this important detail! It took some time and effort to get here, but the upcoming 8.0.0 version (this week) will feature an implementation of the AISC specification, including compression flange buckling and other relevant checks for beams and columns. You will be able to compute flexural strength by entering the unbraced length Lb value. Of course, we've added more bells and whistles too. :)
