Free · Designed for iPad. Not verified for macOS.
Eleven professional calculators for real electrical and plumbing work — NEC 2023 & 2026 data, zero sign-ups, works offline. One purchase, yours for good.
TradesMath puts eleven professional calculators in your pocket — built for
electricians and plumbers who need fast, code-aware answers on site.
**NO INTERNET REQUIRED.** Every calculator works with zero connectivity —
basements, new construction, remote sites, dead zones: no signal is never
a problem.
ELECTRICAL (8 TOOLS)
Ohm's Law · Voltage Drop · Conduit Fill · Ampacity · Box Fill · Residential
Load Calculations · Motor Circuit (430) — each with the inputs you actually
use in the field.
PLUMBING (3 TOOLS)
Pipe Volume · Rolling Offset · Head Pressure — the numbers you'd otherwise
look up by hand.
DUAL EDITION: NEC 2023 & 2026
The built-in Edition tab keeps calculations aligned with both NEC 2023 and
NEC 2026 data, with source worksheets so you can trace every result. Switch
editions to match the code cycle your jurisdiction enforces. When the code
changes, TradesMath updates — you don't have to.
BUILT FOR THE TRUCK, NOT THE OFFICE
• 100% offline — no internet required, no account, no sync, no analytics,
no tracking
• Unit converter built in
• Every result card includes a "not a substitute for the NEC" reminder —
these tools support your judgment, they don't replace the code
One purchase. Every calculator, every future update. No subscription.
