Electrician Calc & Report

Electrician Field Toolkit helps residential electricians and small contractors do everyday job-site math and finish a client-ready electrical report—even with weak or no cell service. EVERYDAY FIELD CALCULATORS Need a quick check before you pull wire or size a load? Use Ohm's law (V = I × R), power (P = V × I), kW-to-amps for single-phase or three-phase with power factor, and voltage-drop percent from meter readings. Formulas are plain and offline so you can verify the numbers with your meter. WORK WHERE THE JOB IS Basements, crawlspaces, attics, and new builds often have weak signal. Customers, checklists, annotated photos, materials, hours, signatures, calculators, and PDF export all run on your phone. No account. No cloud login. INSPECT WITH AN ELECTRICIAN CHECKLIST Start from a residential electrical inspection checklist covering the panel, breakers, wiring, outlets (including GFCI/AFCI checks), and safety devices. Mark each item Pass, Fail, N/A, or Replace Recommended. Failed items keep a note so the homeowner sees why something failed. PHOTO PROOF THAT CLIENTS UNDERSTAND Snap the panel, a double-tapped breaker, or a cracked receptacle, then mark it up with arrows, circles, rectangles, text, and numbered callouts. Annotations save into the image so the evidence travels with the report. MATERIALS, HOURS, AND SIGNATURES ON SITE Log what you used with quantity and unit. Start and stop a job timer so billable hours don't get lost. Capture customer and electrician signatures and embed both in the PDF. CLIENT-READY PDF IN MINUTES Generate a multi-page US Letter report with your company name, phone, license number, and optional logo; pass/fail summary; failed items with photos and notes; materials and hours; then signatures. Share from the phone by email or any app your office already uses. COMMENT LIBRARY FOR FASTER NOTES Insert plain-language phrases when you mark a fail—overheating at the panel, missing GFCI in a bath, reverse polarity—so you type less with gloves on. Pro unlocks favorites and custom phrases. PRO (ONE-TIME PURCHASE) Free lets you try the workflow on a limited number of projects. Pro removes the project cap and ads, unlocks custom checklist editing, comment favorites, and cleaner client PDFs. Pay once—no subscription. PRIVATE BY DESIGN Job data stays on the device. Export a local ZIP backup when you change phones; nothing uploads unless you choose to share a report.
