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.
Calc Tools
Read full descriptionHide full description
A practical construction calculator for carpenters, builders and contractors. Work out concrete quantities, stair dimensions and baluster spacing from the measurements you already have. Whether you're framing a wall, planning a deck or estimating a concrete pour, Calc Tools brings 16 everyday calculators together on your iPhone and iPad. Choose a tool, enter your dimensions and get a clear result with a diagram to guide your measurements. PLAN YOUR NEXT JOB • Concrete: estimate slab volume or concrete for round posts, holes and circular pads, including a waste allowance. • Stairs: find riser and tread counts, riser height, total run, pitch and an overall stringer-span estimate. • Balusters: work out a count and equal clear gaps from your span, baluster width and maximum gap. • Decking: estimate board count and total purchase length with an allowance for waste. • Gravel, soil and asphalt: estimate volume for paths, beds and other projects. Use your chosen density to calculate gravel or asphalt weight. CHECK DIMENSIONS AND LAYOUTS • Check Square: find the diagonal, area and perimeter for a rectangular layout. • Right Triangle: solve missing sides and angles from the measurements you know. • Pitch: calculate slope and angle from rise and run. • Equal Spacing: lay out evenly spaced points by count or target spacing. • Raked Wall: calculate full wall heights at stud positions from heights or pitch. • Running Dimensions: turn a starting measurement and interval into a list of layout marks. • Dumpy Level: calculate reduced levels from benchmark and staff readings. • Area: calculate rectangular area with an optional waste allowance. METRIC AND IMPERIAL MEASUREMENTS Work in millimeters, meters, inches, or feet and inches. Enter mixed fractions and choose inch display accuracy from 1/2 to 1/64. Convert your entered measurements between units while retaining their full calculation precision. READY WHEN YOU NEED IT Calculations work offline. Find a tool with search and categories, keep favorites within reach, and save named calculations with their inputs and results. Reopen a saved calculation or share the result with your crew. All 16 tools are included. No account, subscriptions or in-app purchases. Light and dark appearances keep the interface clear on iPhone and iPad. Results are estimates. Verify dimensions, material allowances and local building requirements before use. Raked-wall heights and stringer spans require separate cutting and fitting allowances.
