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.
