About Journeyman Voice Calculator
YOUR HANDS ARE BUSY. YOUR VOICE ISN'T. Every tradesperson knows the drill. You're mid-cut, mid-pour, mid-install. You need a quick calculation. And your phone is either in your pocket under two layers, or your hands are too grimy to tap a screen. Journeyman is a construction calculator you talk to. 155 TRADE FORMULAS. ONE INPUT: YOUR VOICE. "How many studs for a 20-foot wall?" Sixteen studs. "Board feet in a 2x6x12?" Twelve board feet. "Concrete for a 10 by 12 slab, 4 inches thick?" 1.48 cubic yards. Ask like you'd ask the person next to you. FRACTIONS FIRST Every answer comes in tape-measure fractions. 3-1/2", not 3.5. 1-3/4", not 1.75. Because the tape on your belt doesn't have a decimal point. SHOW THE MATH Tap any answer to see the step-by-step breakdown. The formula, the inputs, the work. Learn the math. Check the math. Trust the math. WORKS EVERYWHERE YOU WORK Offline. No account.
