WireMind Pro

Free 14-day trial, then a one-time unlock — no subscription. Offline AS/NZS 3000 & 3008 calcs: cable size, voltage drop, demand, earthing. Every answer cited, on-device.

WireMind Pro is a field-first electrical calculator built around the Australian/New Zealand Wiring Rules (AS/NZS 3000) and AS/NZS 3008.1.1 cable selection — including the 2025 edition. It's made for sparkies on the tools: large, glove-friendly controls, a sunlight-readable display, and answers in seconds — fully offline, on the job site, with no signal.

Every number and every citation comes from a deterministic calculation engine — never guessed. An optional on-device assistant only turns your plain-language request into calculator inputs and explains results in readable terms; it never invents a value or a clause. Everything runs on your iPhone: no account, no internet, nothing leaves the device.

WHAT IT DOES • Voltage drop — AC and DC, with operating-temperature and reactance refinement • Conductor area, Ohm's law, power and unit conversions • Cable sizing, maximum demand, protective-device coordination, earthing (adiabatic), conduit fill — you enter the value from your own copy of AS/NZS 3008, the app does the derating and the math (no licensed table is bundled — private and licence-clean) • Three ways in: guided forms, a fast keypad, or just ask • Save calculations to projects; export clean, AS/NZS-cited PDFs • Pick your edition: AS/NZS 3008.1.1 2025 / 3000 2018 / 2007 / 2000 / 1991

PRICING Try every feature free for 14 days. After that, a single one-time purchase unlocks the app for good — no subscription, no recurring charges.

WireMind Pro is a calculation aid. It does not replace the AS/NZS 3000 standard, a licensed electrician's judgement, or your electrical safety regulator.
