### 5/5 — Fast and Simple Tool

*2026-05-27*

A very useful app for civil and structural engineers. It makes complex calculations like slenderness ratio and beam formulas, quick and easy with a clean interface. Great for students and professionals who need fast engineering references on the go

**Developer response:** happy to hear 😎

### 5/5 — Must need app for architecture design

*2026-05-17*

This is a must-have app for all architects and civil engineers. I was in the middle of work and struggling to look up each calculation, and this app came in so handy and has every single variety of the structural calculations required, either for constructing buildings, bridges, roadside extensions, for anything almost.

**Developer response:** happy to hear😎

### 1/5 — Waste app

*2022-12-28*

No use in this app, please don’t download it
It asks you to pay for all basic need for structural

### 5/5 — Excellent

*2020-06-08*

Excellent Work. I have paid INR 249.00 to unlock all 58 Calculators. I intend to buy the piling calculator soon. Keep up the good job.

### 1/5 — Tradução ruim
