BuilderCalc
Read full descriptionHide full description
The construction calculator a contractor actually uses on the job site — tile, drywall, concrete, paint, framing — every material estimate, with waste built in. Tap a project. Answer 2–3 questions. BuilderCalc tells you exactly how much to buy — humanized ("Buy 3 gallons, about $90–$140"), the shopping list to bring, and the mistakes that cost real money every year. FIVE GUIDED PROJECT FLOWS • Paint a room — wall area minus openings, primer + coats, gallon estimate • Tile a bathroom — square footage, box count, waste factor, grout volume • Build a deck (Pro) — joist spacing, beams, posts, footings, decking, fasteners • Install drywall (Pro) — sheets by room, screws, mud, tape • Pour a concrete slab (Pro) — slab, footers, columns, bags or yards EVERY FLOW INCLUDES • The humanized result, not just decimals • The shopping list to bring to the hardware store • The mistakes to dodge — sourced from JLC, Fine Homebuilding, This Old House, and the IRC PLUS 14 PRO CALCULATORS UNDERNEATH Tile · Drywall · Concrete · Paint · Flooring (LVP, hardwood, laminate, carpet) · Framing (studs, plates, headers) · Roofing (squares, underlayment, ridge cap) · Layout (diagonal squareness, stair stringer, rake/run/rise) · Materials waste · Square footage · Conversions · Volume · Coverage · Cost-per-unit WHO IT'S FOR Contractors, remodelers, handymen, framers, finish carpenters. Homeowners running a real project. Anyone who'd rather take an extra coffee break than re-measure for the third time. FREE vs PRO Free forever: paint and tile flows + all 14 calculators. Pro unlocks deck, drywall, and concrete flows; saved-job worksheets; cost-per-square-foot tracking. One-time or subscription. Subscriptions auto-renew until cancelled. Manage in your Apple ID Subscription Settings. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://doublevision.company/privacy OFFLINE. NO ACCOUNT. NO ADS. The job site doesn't always have signal. Neither does this app, by design.
