Tradesman Pro

Tradesman Pro is a completely free precision layout calculator built specifically for plumbers and pipefitters. Designed for job site efficiency, it handles standard and rolling offsets, triangle layout, and everyday feet-and-inch math — with full support for fractional inches and fitting take-offs.

Whether you're running a 22°, 45°, or 60° offset, rolling a bend around an obstruction, or just adding up a run off the tape, Tradesman Pro lets you work in feet, inches, or mixed fractions and see results instantly — with the full formula behind every answer.

THREE CALCULATORS IN ONE

OFFSET CALCULATOR • Travel and Advance for 22°, 45°, and 60° bends • Rolling offset calculations using rise and run • Enter take-offs as one combined total, or separately for each fitting • Live "converted to inches" and "offset minus take-off" readouts as you type • Toggle results between inches and feet/inches

TRIANGLE CALCULATOR • Right triangles and general triangles (SSS, SAS, ASA, AAS) • Solve unknown sides and angles for custom angles and compound bends • Interactive pinch-to-zoom diagram that redraws as you enter values • Perimeter, area, and triangle type, plus heights, medians, angle bisectors, inradius and circumradius

FEET-INCH CALCULATOR • Add, subtract, multiply and divide measurements directly — no converting to decimals first • Dedicated Feet, Inch, and fraction keys, so you never need the text keyboard • Running tape of every calculation, saved between sessions — tap any line to bring that answer back down • Multiply two lengths for square footage, or three for cubic feet and cubic yards • Divide a run into equal parts, or find how many times one length fits into another

BUILT FOR THE JOB SITE • Fractional or decimal display, with rounding to 1/8", 1/16", or 1/32" • Live updates as you type • Tappable formula explanations for training and clarity — copy the full step-by-step breakdown into notes or a text • Clean, high-contrast interface optimized for job site readability • Full Dynamic Type support for larger text • Works on iPhone and iPad • Completely free — no ads, no subscriptions, no accounts, no paywalls

Whether you're laying out a job, double-checking your math, or teaching apprentices, Tradesman Pro makes it faster and easier to get the job right the first time.
