Rework for failing city code is the tax on getting it wrong — wasted material, a second trip, a slipped schedule, and a callback the customer remembers. OHMIE exists to erase it, one code-checked line item at a time.

How it works
Nameplate
Nameplate
to material list.
Three steps, one flow. Watch the app move from a question to a code-checked list to a documented job — the same path you'll walk on site.
Step 01
Answer the knowns
Pick the job, tap through a handful of plain-language questions — one per card, the way you'd read a nameplate. Skip what you don't know.
Voltage · amperage · phase · environment · OCPD
Step 02
OHMIE sizes & checks the code
A deterministic engine works the ampacity, EGC, conduit fill and voltage drop, applies the NEC and your state's amendments, and returns a sized list — every line citing its section.
310.16 · 250.122 · Ch. 9 · voltage drop ≤ 3%
Step 03
Work it, then document it
Check off materials, override quantities, add what you grabbed off the truck, attach photos. Finish with a planned-vs-used report you can email the office or the inspector.

Answer the nameplate questions; OHMIE returns a full material list with wire gauge, breaker, conduit fill and voltage drop already worked out — and every line carries the NEC section behind it, so you can check the work against the book.

The job address sets the code. OHMIE layers each state's own amendments on top of the NEC — primary-source verified against the state's authority, not scraped from an aggregator. That discipline has already caught roughly a quarter of the trackers' claims wrong.

03The Job Ticket
+
The office builds the job in the same app and hands it off as a link, a scannable QR code, or a file. It drops straight into the field wizard, pre-filled. Nothing routes through a cloud — the job travels as data.

04Planned vs. used, on record
+
Override any quantity, add the parts you actually pulled, attach completion photos. The final report is a clean planned-vs-used audit trail — emailed as a real table, not a wall of text — that protects the company, the foreman and the journeyman.

Local & city codes are never checked in any state — always confirm current rules with your AHJ before rough-in. Codes change on their own schedule; this reflects our research as of Aug 2026.
Why a pro can trust it
Not a chatbot.
A deterministic engine, reviewed by a master electrician.
OHMIE doesn't guess. Every result comes from code tables and sizing rules written into the app, then reviewed line-by-line by a master electrician who trains the trainers of journeymen. Plain language leads; the citation always follows.
Plain language first
Simplest-but-accurate wording a first-year journeyman understands, with the exact NEC section attached to every line.
Primary-source verified
State editions and amendments are read from the state's own authority — not an aggregator. That's already caught a quarter of trackers' claims wrong.
You stay responsible
OHMIE is reference guidance. Local codes and your AHJ take precedence; final responsibility for compliance and workmanship stays with the installing electrician.
For crews & contractors
Every journeyman,
Every journeyman,
a master's takeoff.
OHMIE isn't just for the electrician in the field — it's how a shop holds every crew to one standard. The takeoff doesn't depend on who's holding the phone, so the job comes out code-correct whether it's your 20-year vet or your newest hire.
Margin
Kill the rework tax
A callback is pure margin erosion — the truck roll, the redo labor, the wasted material, the unhappy customer. Cut the revisits and every job keeps the profit you bid it at.
Throughput
More jobs per week
Takeoffs in minutes on site — not a trip to the counter and back for the part you forgot. Faster jobs mean more jobs, and speed is billable.
Onboarding
New hires ramp faster
A second-year does master-level takeoffs on day one, so your senior electricians spend less time double-checking and more time in the field.
Rolling it out to a crew? Team access is built for the whole shop — one standard across every truck.

The best investment in the box — or nothing lost.
We're confident OHMIE is the highest-return tool you'll carry, so we're taking the risk off you: run the full app on real jobs for 30 days, free. If it hasn't paid for itself before the month is out, cancel — you're out nothing but the callbacks you didn't make.
- The full app, no feature limits, for a full 30 days
- Not charged until day 31 — cancel before then and you pay nothing
- One inspection you pass the first time more than covers a year of it
Pricing

Lifetime
$499.99once
Pay once. Yours for good — no renewals, ever.

How the plans work
- Switch any time. Move between monthly and annual whenever you like — you only ever hold one, and the App Store sorts out the balance.
- The free trial needs a payment method. Both subscriptions start with 30 days free. Your Apple ID is set up at signup but isn't charged until the trial ends — cancel any time before then and you pay nothing.
- Subscriptions renew automatically at the same price unless cancelled at least 24 hours before the period ends. Cancel in your Apple ID settings, or from inside the app.
- Lifetime is separate. It's a one-time purchase, so it has no trial and never renews. Already subscribed and switching to Lifetime? Cancel your subscription afterwards so you're not paying both — the app will remind you.
- Prices are in US dollars and shown in your local currency by the App Store. Introductory pricing; final pricing confirmed at launch.
Outfitting a whole shop? Team access is priced for the crew — one standard across every truck.

About
Built alongside the trade, for the trade.
OHMIE is built alongside a master electrician who trains the people who train journeymen — the code content comes from the trade, not a guess. The premise is simple: the plain-language distillation of the code is the product — a precision instrument for the field, not another template app.
We're piloting with working electricians now. If you run a crew, teach the trade, or just want fewer callbacks, we'd like you in the room.
