Contact us
Need help, found a bug, spotted a calculation you'd like double-checked, or have a suggestion? Email caglarbozkurt@outlook.com and we'll get back to you, usually within a few days. It helps to include your device model, iOS version, and the calculator and inputs involved.
What can Wireman do?
Wireman bundles 15 electrical calculators and a searchable NEC reference: wire / conductor sizing with derating, circuit sizing, voltage drop, conduit fill, conduit bending (offset, saddle, stub-up), box fill, motor circuits, transformer sizing, 3-phase power, available fault current, dwelling load, EV charger circuits, grounding & bonding, Ohm's law, and unit conversions. Every result shows its worked formula and the NEC section behind it.
Is it accurate? Can I trust the numbers?
Every calculator is built on the published NEC formulas and tables and shows the section it's based on so you can check it. That said, Wireman is a reference tool, not a substitute for the adopted code — always verify against your local NEC and amendments, and use your judgment as a licensed electrician, before performing work.
What is Wireman Pro, and is it a subscription?
The everyday calculators and the full NEC reference are free. Wireman Pro is a one-time purchase — not a subscription — that unlocks the advanced calculators (motor, transformer, fault current, dwelling load, EV charger, and grounding) and includes every current and future NEC edition, with no recurring fees.
I bought Pro on another device / reinstalled. How do I get it back?
Open Settings in the app and tap Restore purchase. As long as you're signed in with the same Apple ID you bought it with, Pro will unlock again at no charge.
Does it work offline?
Yes. Every calculator and the reference work fully offline — no internet connection required. (An internet connection is only used the one time you buy or restore Pro.)
Does Wireman have ads or track me?
No. There are no ads and no tracking. Your inputs stay on your device. See our Privacy Policy for the full detail on the limited data involved in a Pro purchase.
