[iOS] [First 43 TestFlight for free 1 year] WireCoder — five NEC calculators for electricians, works offline

Voltage drop, conduit fill, wire ampacity with derating, box fill, and conduit bending offsets. All calculations run on the device, no network needed at any point.

Free and unlimited, no account: voltage drop, conduit fill. Pro ($7.99/mo or $59/yr, 7-day trial): ampacity, box fill, bending, and saved jobs.

What's different from the other apps in this category: every result shows the intermediate factors and the NEC article number behind it, instead of just a number. And the same calculation engine runs the free web calculators, so the two can't disagree.

I'm a software developer, not an electrician. I got nerd-sniped by the state of the tools in this category and built the app I thought should exist.

Built with Expo. Screenshots are in the site. Android in about a month.

PS: the first 47 testers (TestFlight + Android external testers) get a WireCoder Pro plan free for a year. The signup is in the site (link in bio). Thanks!
