Rectangular Beam is a structural engineering tool for reinforced concrete beam design, providing reinforcement and deflection calculations on iOS.
The App DNA
What makes this app unique?
The tool removes the friction of desktop-based structural analysis for engineers in the field, though current launch failures prevent it from serving this need effectively.
For Civil and structural engineers requiring mobile tools for reinforced concrete beam design and analysis.
What does it look like?
Key features
Calculates required reinforcement for tension and compression zones.
Plots strain distribution and provides epsilon values for each rebar layer.
Computes crack width and beam deflection based on applied moments and forces.
How much does it cost?
Paid model at $4.99 per download, targeting professional engineers with specific structural design utility.
Velocity
Dormant developmentnew contentShow more...
Rectangular Beam has seen no development activity for 740 days. The last recorded update was a minor feature addition, and the lack of any subsequent releases indicates the project is no longer being actively maintained. There is no evidence of ongoing support or operational updates.

Key takeaways for Rectangular Beam
Where is it heading?
The mobile structural engineering market is consolidating around tools with active update cadences that ensure compliance with current building codes. Rectangular Beam's maintenance-mode status and launch failures leave it exposed to abandonment by its professional user base, which will likely lead to total churn by Q4.
- The 24-month update gap (last release August 2024) signals a lack of active maintenance, which erodes professional trust in the tool's accuracy.
- Critical launch failures in the latest version prevent usage, which compounds the negative sentiment already present in the user base.
The SWOT
- Specialized structural analysis algorithms for strain distribution
- UI refresh to capture engineers seeking portable tools

The 1-star rating is a secondary risk…
Read the full takeSince the last report: The product's status has shifted from a maintenance-focused recovery plan to a formal recommendation for sunsetting, driven by the persistent 24-month development gap and critical launch failures.
Bottom line
Rectangular Beam provides niche engineering utility, but the current launch failures and 24-month maintenance gap render it unusable for professionals [1, 2]. Sunset posture is appropriate until a resource-light maintenance cycle can restore basic functionality.
