Concrete & Gravel Calc

Concrete & Gravel Calc is a handy estimation app built for contractors, builders, and DIY users. It helps you calculate concrete and gravel quantities accurately in seconds—so you can skip spreadsheets and stop guessing. Choose a calculator, enter your measurements, and get results right away.

The app supports direct measurements and lets you switch units anytime. Enter in feet and inches or meters and centimeters, depending on your preference. A clean, modern layout makes it easy to work on-site, and the app runs without an internet connection.

Highlights

• Imperial/Metric toggle for unit switching
• Adjustable waste factor (0–25%) to better match real job conditions
• Bag calculator to estimate how many 40 lb, 60 lb, or 80 lb bags you need
• Gravel weight estimates with density presets such as crusher run, pea gravel, river rock, and more
• Save and label calculations for quick access later



• Cost estimates using your custom price per yard, ton, or bag
• Job-site friendly interface designed to be quick to read and easy to use
• Offline support (no internet required)

Key Features

The app keeps estimating simple. First, select the shape you’re working with: rectangular slab, circular pad, footing, wall, or trench. Then enter length, width, depth, and any reinforcement allowances. As you type, the calculator shows volume and converted units in real time.

Inputs are built for touch use. You’ll find large entry fields, unit selectors that fit the context, and keyboards that help reduce mistakes while you’re entering measurements at the job site.

For sharing and documentation, you can copy results to the clipboard and view a clear summary of key values. Paste your numbers into texts, emails, or procurement lists.

If you repeat estimates often, you can save labeled calculations. With the Pro upgrade, you can also share saved results via text or email.

The interface prioritizes readability and speed: high-contrast text, simple labels, and a clean layout that remains easy to read outdoors and while wearing PPE. Measurement inputs are organized to match how people typically take dimensions in the field, and result panels highlight the most important information first.

Accessibility is taken into account with large touch targets and support for displaying values in either metric or imperial formats for mixed teams and international work.
