Rafter & Framing Calc: BuildX
2h agoBuildX replaces your notepad, regular calculator, and a stack of separate apps with 15 trade‑focused tools for real jobsite math. It handles stairs and IRC rise/run checks, stud spacing, rafters, slope and grade, concrete and footing/rebar, roofing, drywall, fencing, board‑feet, cut‑list optimization and more. Users can type measurements in feet‑inch‑fraction format (e.g., 5' 6‑3/8") without converting to decimal, save projects for later, export results to PDF, and hand off calculations to the TradeBill invoicing app. The app works offline, requires no accounts, and provides a full history of calculations.
