Site Calc Pro

Site Calc Pro is a practical construction calculator built for fast jobsite math, material estimates, layout work, and project-based calculation history.

It is not just a calculator that gives you the last answer. Site Calc Pro keeps an editable tape of your work, organized by project, so you can check previous calculations, reuse entries, duplicate results, copy your tape, and come back to the numbers later.

Built for real construction workflow
Site Calc Pro is designed for the repeated calculations builders, contractors, carpenters, and estimators do every day. Work in familiar units, move quickly between feet-inch fractions and metric, solve practical layout and estimating problems, and keep an editable record of your calculations by project.

One paid app purchase. No subscription.

CALC + TAPE WORKFLOW

Site Calc Pro is built around two main sections:

Calc
Fast construction calculator input for dimensions, units, layouts, materials, roofing, stairs, shapes, costs, wastage, and conversions.

Tape
A project-based tape where your calculations can be reviewed, edited, duplicated, saved, copied, and organized instead of being lost after the next calculation.

WHY USE SITE CALC PRO?

Construction math is often not difficult because you do not know the formula. It is difficult because you are busy, interrupted, switching units, checking estimates, repeating similar calculations, and trying not to lose track of the numbers.

Site Calc Pro is built to make that work faster and clearer.

Calculate in feet-inch fractions or metric. Solve practical construction layouts and estimates. Save the working, not just the result.

From the developer of Construction Calc Pro, Site Calc Pro is a serious paid utility for builders, carpenters, contractors, estimators, tradespeople, and anyone who needs dependable construction calculations on their phone.
