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.

Wish you could have more time? Now you can! We save people just like you over 1 hour per day using Flexblocks! Flexblocks is an auto-scheduling app designed to optimize your day so you waste less time procrastinating. Here's how it works: When you have something to get done with a start and end date it goes in your calendar, and you're extremely likely to complete it, but tasks that have deadlines like your annoying math homework or physics lab don't, hence they go on to-do lists. The reason your math homework ends up being done right before the deadline is because you brain needs to see time set aside.. Introducing Flexblocks! Flexblocks fixes this problem by instantly scheduling timeblocks for you to complete these tasks before the deadline. Unlike any other apps, we learn what times work best for you to create the perfect schedule everytime! ------------------------------- We would love to hear feedback about the app. If you have any questions or concerns please reach out via any of the channels below: Instagram: @flexblocks Email: admin@flexblocks.app Notes: At present, all of our plans are paid because as a business we need to be able to pay the team to continue adding incredible features to improve your experience. The student plan is discounted significantly to allow all students access to this incredible software. Improvements to the auto-scheduling feature, calendar integrations, and re-occurring events are coming in the VERY near future. Current use at this stage in the development will enable us to bring these features to market much faster.

Verdict

The call

The clearest difference is price: Flexblocks at Free against Deflection Pro's $19.99. Flexblocks also leads on review sentiment (100% vs 69%) and update cadence (every 10 days vs every 5 weeks). Deflection Pro's advantage is rating (4.7 vs 1.0) and in-app purchases (none vs 3). On iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

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 1, so its average is the more settled of the two. Written reviews complicate that: 69% of Deflection Pro's written reviews are positive against 100% of Flexblocks's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Deflection Pro ships an update every 5 weeks, Flexblocks every 10 days. The most recent releases landed on September 17, 2026 and June 7, 2026 respectively.
