Take the guesswork out of concrete pours, site layout, and material costs. Whether you're pouring a backyard shed pad, framing footings, or managing large commercial pours, Concrete Calculator delivers instant volume takeoffs, bag counts, labor estimates, and professional client quotes—right from the job site. Version 2.0 is a complete overhaul built specifically for modern iOS and iPadOS devices, featuring an intuitive 3D dimensional interface, a built-in feet-inch-fraction construction calculator, and comprehensive project quoting tools. POWERFUL TRADE ESTIMATORS Concrete Slabs & Walls: Enter length, width, and thickness in real tape-measure fractions (e.g., 24' 6" × 20' 8" × 4-1/2") to calculate exact cubic volume, ready-mix yardage, or pre-mix bag counts. Columns & Sonotubes: Fast cylindrical footing estimators with multi-unit quantity multipliers for pier and post-hole runs. Aggregates & Gravel: Calculate base material requirements in cubic yards, cubic feet, or tons. Block & Brick: Instant unit counts and mortar takeoffs for standard masonry assemblies. SITE LAYOUT & GEOMETRY Pad Squaring & Diagonals: Quickly square up forms before pouring using built-in Pythagorean layout tools. 2D Areas & Angles: Calculate complex multi-shape site footprints and compound areas with dedicated dimension readouts. 3D Volumes: Dedicated calculators for prisms, cylinders, truncated cones, and custom shapes. BUILT-IN CONSTRUCTION CALCULATOR Traditional jobsite keypad with dedicated unit keys (Yards, Feet, Inches, Centimeters, Meters). True fractional entry down to 1/16" with running history tape. Multiply linear dimensions directly into cubic volume (e.g., 24'6" × 20'8" × 4-1/2" = 7.03 YD³). PROJECT MANAGEMENT & CLIENT QUOTES Organize calculations under dedicated job folders (e.g., "Smith Driveway & Garage"). Build detailed client estimates combining materials, waste margins, and customizable labor hourly rates. Maintain a custom Material Database with localized pricing and density specs. Export and share clean estimates and material orders directly via email or message. DESIGNED FOR FIELD & OFFICE Native iPad Multitasking: Full 3-column split-view layout for desktop-grade estimating on 13" iPad Pro and Air. Full Dark & Light Themes: High-contrast modes optimized for bright sunlight outdoors and low-light plan reviews indoors. Universal Units: Seamless switching between Imperial (feet, inches, fractions, yards) and Metric (meters, cm, mm, m³). Built for concrete finishers, general contractors, masons, landscapers, and serious DIYers who need jobsite precision without the math errors.
