FieldDojo: Trade Calculators

Most trade calculator apps do one trade and charge you for the privilege. FieldDojo does four. Electricians, HVAC techs, plumbers, and builders get 57 field-ready calculators in one app — each result showing the number, the formula, and the exact code reference behind it. Online or off. WHAT YOU CAN CALCULATE • Electrical (14) — Wire size, voltage drop, conduit fill, panel load, breaker size, motor FLA, ground wire, transformer kVA, three-phase current, and dwelling load, cited to the NEC (Table 310.16, Chapter 9, Article 220, and more). • HVAC (8) — BTU heat load, duct sizing, refrigerant charge (subcooling/superheat), heat loss, tonnage, SEER savings, CFM per ton, and air changes per hour, referenced to ASHRAE and AHRI. • Plumbing (9) — Supply pipe sizing, flow rate, drain slope, gas pipe size (NFPA 54), septic tank size, water heater sizing, and fixture units per UPC/IPC tables. • Construction (26) — Concrete volume and bags, board feet, stud count, drywall, roofing squares and pitch, stairs, rafters, decks, fences, tile, pavers, retaining walls, insulation R-value, and more — waste factor included. BUILT FOR THE JOBSITE • Works offline. No signal in a basement or mechanical room? Every calculator still runs — the code tables live on your phone. • Shows its work. Each result displays the formula and the standard behind it, so you can defend the number to an inspector. • Imperial or metric in one tap, applied across every calculator. • Prices the job as you go. Set your material costs once and FieldDojo estimates the total with every calculation. • Made for gloves and sunlight. Big tap targets, high contrast, readable on a roof at noon. • No ads. Your calculations stay on your device unless you turn on cloud backup. FIELDDOJO PRO Every calculator works without a purchase.

WHO IT'S FOR Licensed electricians, HVAC and refrigeration techs, plumbers, general contractors, remodelers, and apprentices who'd rather get the number right the first time than redo it after inspection.
