SignOnSite vs WireMind Pro

SignOnSite is an app that matches workers in the construction industry with nearby construction companies running and managing construction sites. The SignOnSite app revolutionises worksite safety by allowing you to SignOn from anywhere on site - directly from your smartphone. By creating an account with SignOnSite you can: • check in to any companies sites using the system (without visiting the site office to sign the paper register) • access daily briefings and toolbox talk information posted by the builder for the site • share your account details via a digital site-specific induction form, including the sharing of your credentials and their status • get evacuation notification alerts if an emergency or drill occurs on the site

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.
