Construction Calc Lite vs Construction Pro

Designed by tradespeople, for tradespeople. Construction Calc Lite handles the heavy lifting of jobsite math—fractions, dimensional conversions, framing, and layout—so you can focus on the build. Whether you're a carpenter, concrete finisher, framer, superintendent, or DIYer, Construction Calc Lite delivers fast, accurate jobsite calculations with zero guesswork. WHY TRADES CHOOSE CONSTRUCTION CALC • True Feet-Inch-Fraction Math: Add, subtract, multiply, and divide in full dimensional fractions down to 1/16th (or user-set precision) with automatic reduction. • Seamless Unit Switching: Effortlessly mix Imperial and Metric. Convert feet-inch-fractions to meters, centimeters, or millimeters in a single tap. • Split-Screen Display: View decimal values, feet/inch fractions, memory registers, and scale factors simultaneously in large, high-visibility text. • Visual Cut & Layout Solvers: Dedicated modules for right triangles, miters, arcs, and baluster spacing complete with clear visual diagrams. • 50 Memory Registers & Full History: Never lose a cut list or measurement. Easily recall previous calculations on the fly. DEDICATED MODULES FOR EVERY TRADE • Framing & Layout: Calculate stud, fence post, and baluster spacing (horizontal, angled, or circular). • Miters & Trim: Visual miter and bevel angle calculator for crown molding and finish carpentry. • Geometry & Stairs: Instant solutions for right triangles, diagonals, rafter lengths, arcs, and chords. • Concrete, Volume & Area: Quickly calculate slab volume, footings, room square footage, and block/tank capacities. • Materials & Coverage: Estimate drywall sheets, tile, paint, and material costs with built-in waste allowances. • Smart Blueprint Scaling: Instantly scale plan drawings up or down to true field dimensions. BUILT FOR THE JOBSITE • High-Contrast Display: Large, legible fonts engineered for bright outdoor sunlight or dark crawl spaces. • Works 100% Offline: No cell service required on remote sites.

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/
