Tradesman Pro vs Welding Reference 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.

Welding Reference Pro puts every tool a welder needs in one app — calculators, reference guides, training, and QA checklists. No internet required. No subscription. One price, everything unlocked. CALCULATORS (8) Weld Settings — enter your process, material, and thickness to get amperage, voltage, wire speed, and electrode recommendations for MIG, TIG, Stick, and Flux-Core. Wire Feed Speed — convert between wire feed speed and deposition rate across 6 wire diameters. Gas Flow — get shielding gas type and flow rate recommendations by process, material, joint type, and position. Filler Weight Estimator — calculate pounds of filler metal needed for 5 joint types with waste factors. Unit Converter — 7 categories including length, temperature, pressure, flow rate, weight, heat input, and area. Weld Cost Estimator — estimate labor, filler, and gas costs with your own custom rates. Edit every rate in the app. Heat Input (Pro) — calculate joules per inch with process efficiency factors for SMAW, GMAW, GTAW, FCAW, and SAW. Preheat Calculator (Pro) — input your carbon equivalent elements and thickness to get preheat temperature and crack sensitivity assessment. REFERENCE GUIDES (9) 27 electrodes and filler metals — E6010 through Inconel, searchable by classification, type, or application. Electrode Guide, Welding Symbol Decoder (18 AWS A2.4 symbols), Joint Preparation Guide (13 joints), Weld Defect ID (10 defects with causes and fixes), Gas Reference Chart, Material Properties (18 materials including duplex and nickel alloys), NDE Methods, Heat Treatment Reference, and Pipe Welding schedules. TRAINING ACADEMY 6 study modules with spaced repetition: Welding Fundamentals, Electrode Mastery, Blueprint Reading, Metallurgy, Weld Quality, and Code Awareness. Questions you get wrong come back sooner. Track your streak and progress. EXAM PREP (Pro) Practice for CWI (56 questions), AWS D1.1 (85 questions), ASME Section IX (88 questions), OSHA Welding Safety (56 questions), and Welding Math (45 questions).
