Construction Pro is a construction calculator for iPhone and iPad. Work with feet, inches and fractions, calculate roof pitch and rafters, plan stair rise and run, and find diagonals for layout work. FEET, INCHES & FRACTIONS Add, subtract, multiply and divide measurements without converting every length to a decimal first. Convert decimal measurements to feet-inch fractions for tape-measure readings. ROOF PITCH & RAFTERS Calculate roof pitch, slope, common rafter lengths and cut angles. Estimate roof area and roofing squares, with a waste allowance for material planning. STAIR RISE & RUN Calculate riser height, tread count, total run and stringer length from your project dimensions. Check the layout against your plans and locally adopted building requirements before cutting. RIGHT TRIANGLES & DIAGONALS Find a diagonal or a missing side using right-triangle calculations. Work with 3-4-5 triangles and compare layout measurements when checking corners for square. MATERIAL ESTIMATES Estimate concrete volume, board feet, drywall, flooring and other job materials. Keep units and waste allowances visible while planning quantities. KEEP THE CALCULATION WITH THE JOB Save calculations in projects, measure from blueprint takeoffs and create bid PDFs with line items, markup and tax. Use Field Mode for a high-contrast calculator layout. Calculator tools work offline. Some tools, project-saving and export features require Pro. Purchase options and access are shown in the app. Room scanning requires a compatible LiDAR-equipped device. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
