Ratings and reviews

This app has become a useful part of my daily site work. I can quickly check different construction quantities without doing everything manually.

One of the most useful construction calculator apps I’ve used. Simple, fast and accurate.

The app does not provide the detailed metal/steel section calculation features I expected. It lacks important options such as equal and unequal angles, SHS/RHS dimensions, detailed section-wise calculations and material/grade-based metal calculations. I purchased the PRO subscription expecting these construction and steel calculation features, but after using the app I found that it does not meet my requirements. I would therefore like to request a refund.

What’s new

Your results now speak your region's units.

• Concrete, sand and aggregate in cubic yards or m³ — and cement in the bag you actually buy: 94 lb, 50, 40, 25 or 20 kg
• Water in gallons or litres, steel in lb or kg
• Share, PDF, Excel and your estimate now match exactly what's on screen
• Rates priced per the unit you buy in
• Fixed: UK and Australia cement costs, Canadian 10M bars, imperial weights
• Clearer, easier-to-read result tables
