ConstructionTally: Calculator

Every construction calculator in one app, with the math shown. CALCULATORS • Concrete: slab, footing (strip and pads), column or post, and bags for any volume. Bags, cubic yards or cubic metres, plus a ready-mix order. • Framing: wood stud walls and metal stud walls (C-stud and U-track, or CW/UW profiles), with doors and windows: studs, plates or track, headers, cripples, bridging and screws. • Drywall: sheets, screws, tape and joint compound, net of openings, one or both sides. • Paint: litres or gallons for your coats and coverage, rounded to real can sizes. • Block walls: blocks for any wall, with joints and openings. • Room builder: enter a room and its doors and windows once; get framing, drywall and paint together. HONEST NUMBERS • Every result shows the formula and the inputs it used. • "Need" (exact) and "Buy" (whole bags, sheets, studs, cans) are shown separately, with your waste %. • A "check this" warning when a size looks wrong, instead of a silly answer. YOUR UNITS, YOUR REGION • Metric, decimal feet, or feet-inch fractions to 1/16". • US, UK and European bag, sheet, lumber and block sizes. • Works offline.
