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. CONSTRUCTION CALCULATOR FEATURES • Feet-inch-fraction math • Metric entry and conversions • Decimal, fraction, square, cubic, weight, area, and volume calculations • Length, width, and height stored dimensions • Area, volume, perimeter, wall area, room area, and square-up workflows • Cost, percent, wastage, board feet, and material estimating tools • Weight/volume and density calculations • Memory, save, autosave, and project-based tape history ROOFING, RAFTERS AND FRAMING • Pitch, rise, run, and diagonal calculations • Angle, grade, ratio, plumb, and level outputs • Common rafter calculations • Hip/valley and jack rafter calculations • Irregular pitch and irregular jack rafter workflows • Roof area and roof covering estimates • Rake wall and arched wall calculations • On-center spacing support for layout work STAIRS, SHAPES AND LAYOUT • Stair layout calculations • Risers, treads, stringers, total rise, and run workflows • Circle and arc calculations • Polygon calculations • Column and cone area/volume calculations • Crown / compound miter calculations • Degree and DMS conversion support MATERIALS AND ESTIMATES Site Calc Pro includes practical estimating tools for common construction materials and quantities, including: • Drywall • Tile • Paint • Brick and block • Flooring • Fence panels • Posts • Studs • Roofing coverage • Concrete, gravel, and material weight estimates • User-set coverage, spacing, and density values where applicable BUILT-IN HELP Many buttons include long-press help with examples, key sequences, notes, and output explanations. Advanced functions are explained inside the app, so you can learn the workflow without leaving the calculator. 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.

Batch Ledger saves your product specification, target component amounts, measured net weights and later observations together in one local batch record. HOW IT WORKS 1. Open Batch Ledger from Mix. Record a two-part epoxy batch, or explore the clearly labeled illustrative example. 2. Verify the product ratio basis, technical-sheet reference, densities when needed, target weight and scale step. Enter separate net component weights and save. 3. Inspect the recorded ratio difference, add later observations and share the batch report. Each saved batch keeps its original recipe snapshot. Project calculators, mold volumes, pigments, costs, batch planning and resin references remain available. Corrupt ledger files are preserved with new writes blocked. Failed writes do not replace saved observations. WHAT TO KNOW For manually recorded two-part epoxy observations, not UV or catalyst-dosed systems. Weight and volume ratios can differ. Scale resolution is not manufacturer tolerance or proof of scale accuracy. This does not validate cure, formulation, safe batch size or suitability. Never change a product ratio to alter cure time or use the record to repair a mixed batch. Follow the exact product instructions. Up to 500 records are stored locally. iPhone and iPad.
