## What is 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.

### 2.5 — 2026-08-01

NEW: Feet-Inch Calculator

Add, subtract, multiply, and divide feet-and-inch measurements on a proper trade keypad — no converting to decimals first. Every calculation is saved to a running tape you can tap to bring an answer back down, and it's still there next time you open the app. Multiply two lengths for square footage, or three for cubic feet and yards.

OFFSET CALCULATOR
• "Setback" is now called "Advance," with plainer explanations of what Travel and Advance mean on the job
• Enter take-offs as one combined total, or separately for each fitting
• Pick your rounding — 1/8", 1/16", or 1/32" — in Settings

ALSO IN THIS UPDATE
• Negative results now display correctly instead of showing zero
• Measurement fields accept more formats, including 5'6" and 5-1/2
• Various fixes and polish throughout
