NFPA 70 (Official NEC) App
The official digital edition of the NEC published by NFPA. Provides the complete, unabridged code text with the same formatting as the printed book. Good for verifying exact code language, but lacks built-in calculators, AI search, or interpretation aids. Requires a paid subscription ($150+/year).
NEC Quick Reference Apps
Various third-party apps offer condensed NEC references with commonly used tables (ampacity, conduit fill, box fill) in a quick-lookup format. These are useful for fast table checks but typically do not include the full code text, commentary, or cross-references. Most are free or low-cost.
Ugly's Electrical References
The digital version of the classic pocket reference. Includes tables, formulas, and diagrams that electricians have relied on for decades. The app version adds search functionality and bookmarking. Best as a supplementary reference alongside a full NEC app.
Electrical Calculation Apps
Calculation apps eliminate the manual math that slows you down and introduces errors. The best electrical calculators are purpose-built for the trade, with inputs and outputs that match how electricians actually work. Here are the calculations every electrician needs at their fingertips:
Voltage Drop Calculator
Enter wire gauge, conductor material (copper or aluminum), circuit length, load current, and voltage to get the percentage voltage drop and actual voltage at the load. Critical for ensuring compliance with NEC recommendations (3% branch circuit, 5% total). Learn more about voltage drop calculations.
Input: #10 Cu, 150 ft, 30A, 240V
Output: 3.2% VD (232.3V at load)
Wire Sizing Calculator
Determines the correct wire gauge based on amperage, distance, voltage, conductor material, insulation type, ambient temperature, and conduit fill. Factors in derating per NEC 310.15 and recommends the minimum wire size that meets both ampacity and voltage drop requirements.
Input: 50A, 200 ft, 240V, Cu, THHN
Output: #6 AWG (ampacity) → #4 AWG (VD)
Conduit Fill Calculator
Calculates the fill percentage for any conduit type (EMT, IMC, RMC, PVC, FMC) based on the number and size of conductors per NEC Chapter 9. Tells you instantly whether your planned pull is within the 40% fill limit (over 2 wires) and suggests the next conduit size up if needed. See our conduit fill calculation guide.
Input: 3/4" EMT, 4x #12 THHN + 1x #12 GND
Output: 38.1% fill — PASS
Box Fill Calculator
Counts conductor equivalents per NEC 314.16 for devices, grounds, clamps, and fittings in a junction box, then verifies the box volume meets the minimum required. Prevents overfilled boxes that lead to inspection failures and overheating hazards.
Input: 4x #14 conductors, 2 devices, 1 ground
Output: 18 cu-in required — Use 4" square box

Blueprint & Plan Viewing Apps
Paper blueprints are increasingly being replaced by digital plan sets that you view on a tablet or phone. Blueprint viewing apps let you zoom into fine details, mark up drawings, compare revisions, and carry an entire project's worth of plans in your pocket. For electricians, being able to zoom in on panel schedules, receptacle layouts, and riser diagrams on-site is a significant productivity gain.
PlanGrid (Autodesk Build)
Industry-standard construction document management. Upload PDFs of your electrical plans, then view, markup, and share from any device. Automatic version control ensures everyone is working from the latest revision. Supports hyperlinks between sheets — tap a panel schedule reference to jump directly to the panel detail. Paid subscription, typically provided by the GC.
Bluebeam Revu (Mobile)
Professional PDF markup tool popular with electrical estimators and project managers. The mobile companion app syncs with the desktop version for field access. Excellent for takeoffs, quantity counting, and detailed annotation of electrical drawings. Its measurement tools work well for field verification of conduit runs and equipment locations.
Procore
Construction management platform that includes drawing management, RFI tracking, submittals, and daily logs. For electrical subcontractors, Procore's drawing tools let you view plans, log issues, and coordinate with other trades from the field. The platform is typically set up by the general contractor with access granted to subs.
Tips for Digital Blueprints in the Field
- Download offline: Always pre-download plans to your device before going to a job site with poor cell service
- Use a tablet: A 10-12" tablet is the sweet spot for viewing electrical plans on-site. Phones work but are limiting for dense drawings
- Protect your device: Use a rugged case and screen protector. Construction environments are harsh on electronics
- Bookmark key sheets: Flag the electrical site plan, panel schedules, riser diagram, and specs for quick access
Project Management & Job Tracking
For electrical contractors and lead electricians managing multiple jobs, project management apps keep everything organized: schedules, material lists, crew assignments, customer communication, and progress tracking. The right PM tool reduces the time you spend on paperwork and ensures nothing falls through the cracks.
Jobber
Purpose-built for field service businesses. Handles scheduling, quoting, invoicing, GPS crew tracking, and customer communication in one app. Customers can approve quotes and pay invoices online. Popular with residential electrical shops running 1-10 trucks.
Starting at $49/month
ServiceTitan
Enterprise-grade field service management with dispatching, pricebook management, marketing tracking, and reporting. Designed for larger shops that need deep analytics and integration with accounting software. Steeper learning curve but extremely powerful.
Custom pricing (typically $150+/month)
Buildertrend / CoConstruct
Construction-specific project management platforms that handle scheduling, change orders, selections, and client portals. Good for electrical contractors who work primarily on new construction and renovation projects where coordination with builders is critical.
Starting at $99/month
Simple Apps (Trello, Todoist)
For solo electricians or very small shops, a basic task management app can be enough. Create boards for each job, track phases (rough-in, trim, final), and set reminders for inspections. Low cost and easy to start, but lacks trade-specific features like invoicing.
Free tier available
Estimating & Invoicing Software
Accurate estimates win jobs and protect your margins. Modern electrical estimating software lets you build material lists from digital takeoffs, apply labor rates per task, factor in overhead and profit, and generate professional proposals — often right from your tablet on-site.
Electrical Estimating Software (Accubid, ConEst, McCormick)
Dedicated electrical estimating platforms with built-in electrical item databases, labor unit tables, and digital takeoff tools. These desktop-class applications (with mobile companions) are the standard for commercial and industrial bid work. They calculate material costs, labor hours, and overhead for every circuit, device, and fixture.
QuickBooks + Joist / Invoice2go
For residential contractors, QuickBooks handles bookkeeping and payroll while a mobile invoicing app handles the customer-facing side. Create line-item estimates, convert them to invoices when the job is done, and accept card payments on-site. The combination covers most small shop accounting needs.
Flat Rate Pricing Apps
Apps like The New Flat Rate provide pre-built pricing menus for common electrical tasks (outlet installation, panel upgrades, fixture swaps). Electricians present pricing options on a tablet, and the customer selects the tier they want. This removes the guesswork from pricing and improves close rates for service work.
Estimating Best Practice
Regardless of the tool you use, always include a digital record of your takeoff quantities, labor assumptions, and material pricing. When a job runs over budget, comparing your estimate to actual field conditions is the only way to improve your future accuracy. The best estimating apps make this comparison easy with built-in job costing reports.
Ampora — The Electrician's AI Companion
Instant NEC code answers, electrical calculators, and AI troubleshooting. Free on iOS.
Photo Documentation Apps
A picture is worth a thousand words in the electrical trade — especially when a dispute arises about what was behind the drywall before it was closed up. Photo documentation apps go beyond your phone's camera by organizing photos by job, adding timestamps, annotating images with callouts, and creating shareable reports.
CompanyCam
The industry leader for contractor photo documentation. Photos are automatically tagged with GPS location, time stamp, and project. Team members' photos sync to a shared feed organized by job address. Add annotations, create before/after comparisons, and generate photo reports for customers or inspectors. Integrates with Jobber, ServiceTitan, and other PM tools.
Your Phone's Camera + Album Organization
The simplest approach: take photos with your phone camera and organize them into albums by job. Works for solo operators but breaks down quickly with multiple jobs and crew members. No automatic GPS tagging by job, no annotation tools, and no easy way to generate reports. Free but limited.
What to Document with Photos
- Before starting: Existing conditions, panel state, accessible spaces
- Rough-in: Wire routing, box locations, grounding connections
- Hidden work: Anything that will be covered by drywall, ceiling, or concrete
- Label shots: Panel labels, wire markings, equipment nameplates
- Code compliance: Proper separations, support intervals, fill levels
- Problem areas: Existing code violations, damage, unsafe conditions
- Inspection prep: Everything the inspector will want to see before cover
- Final result: Completed installation from multiple angles
Training & Exam Prep Apps
Whether you are studying for your journeyman electrician exam, master electrician license, or continuing education requirements, dedicated study apps make it possible to fit prep into the dead time in your day — lunch breaks, waiting for inspectors, and evenings at home.
Electrician Exam Prep Apps
Apps like Electrician Exam Prep, Journeyman Electrician Prep, and similar titles provide hundreds of practice questions organized by topic (NEC articles, electrical theory, calculations, safety). They simulate the timed test environment and track your scores over time so you can focus on weak areas. Most offer both free question sets and paid premium libraries.
Mike Holt's NEC Training
Mike Holt's code training materials are a staple of the electrical industry. The digital versions include video courses, practice exams, and illustrated code explanations. The subscription-based platform covers NEC articles in depth with practical examples that go beyond rote memorization.
Ampora for Study
While not a traditional exam prep app, Ampora's AI-powered NEC search is an excellent study companion. Ask questions like “Explain the difference between GFCI and AFCI protection” or “What are the dwelling unit small appliance circuit requirements?” and get detailed, code-referenced explanations that deepen your understanding.
YouTube & Video Platforms
Channels like Electrician U, Jordan Farris, and Sparky Channel provide free video training on NEC code topics, installation techniques, and exam preparation. While not an “app” in the traditional sense, the YouTube mobile app provides a massive library of free electrical training content that supplements formal study materials.
Tool & Inventory Management
Lost tools and missing materials cost electrical contractors thousands of dollars per year. Tool tracking apps use Bluetooth tags, QR codes, or GPS to help you know where every tool is, who has it, and when it needs calibration or replacement.
Milwaukee ONE-KEY
If your shop runs Milwaukee tools, ONE-KEY provides built-in Bluetooth tracking for compatible tools, plus the ability to add Tick tags to any tool or piece of equipment. Customize tool settings (speed, torque) remotely, track maintenance schedules, and see the last known location of every tagged item. Free app; works with Milwaukee's connected tool ecosystem.
DeWalt Tool Connect
DeWalt's equivalent tool tracking and management platform. Tracks compatible DeWalt tools via Bluetooth, provides inventory management, and allows custom tool settings. Similar functionality to ONE-KEY but within the DeWalt ecosystem.
Material Tracking
For managing wire, fittings, devices, and other materials across multiple jobs, apps like Sortly or custom spreadsheet solutions help you track what is on the truck, what is on each job site, and what needs to be ordered. Barcode scanning speeds up check-in and check-out.
Supply House Apps
Apps from your electrical distributor (Graybar, WESCO, Rexel, CED) let you check real-time stock availability, place orders for will-call or delivery, and track pricing. Having your distributor's app on your phone means you can order materials the moment you realize you need them — without leaving the job site.
AI-Powered Electrical Tools
Artificial intelligence is transforming how electricians access information and solve problems in the field. AI tools for electricians go beyond simple lookups — they understand context, interpret questions, and provide reasoned answers that account for the specific situation you are dealing with.
How AI Changes the Game for Electricians
Natural Language Code Lookup
Instead of knowing that GFCI requirements are in NEC 210.8, you ask “Where do I need GFCIs in a kitchen?” and get the complete answer with code references. Ampora's AI understands the question and returns the relevant code sections, tables, and exceptions — in seconds.
Intelligent Troubleshooting
Describe the symptoms — “breaker trips when the kitchen dishwasher and microwave run simultaneously” — and AI walks you through a diagnostic sequence: check circuit loading, verify wire sizing, test for ground faults, and assess whether a dedicated circuit is needed per code.
Context-Aware Calculations
AI-powered calculators understand when you need derating applied, when voltage drop limits apply, and which NEC tables are relevant to your specific situation. They do not just compute — they explain the reasoning and flag potential issues.
Learning Companion
Ask “Why does the NEC require AFCI protection for bedroom circuits?” and get an explanation of the code requirement, the fire safety rationale, the historical context, and the differences between AFCI and GFCI protection. AI turns code lookups into learning opportunities.
AI App Comparison
| Feature | Ampora | Generic AI (ChatGPT, etc.) |
|---|---|---|
| NEC-specific training | Purpose-built for NEC | General knowledge only |
| Code citations | Exact section references | May cite incorrectly |
| Built-in calculators | Trade-specific tools | No integrated calculators |
| Offline access | Works offline | Requires internet |
| Current NEC edition | Up to date | May reference old editions |
| Cost | Free (iOS) | Free tier limited; $20/mo for full |
Free vs. Paid App Comparison
Not every app needs to cost money, and not every free app is worth installing. Here is a realistic breakdown of where free apps deliver genuine value and where paying for a premium tool is worth the investment.
Where Free Apps Excel
- ✓NEC AI reference: Ampora provides free AI-powered code lookups, calculators, and troubleshooting
- ✓Basic calculators: Ohm's law, power formula, and simple conversion tools
- ✓Exam prep (basic): Free question banks for initial study
- ✓Tool tracking: Milwaukee ONE-KEY and DeWalt Tool Connect (with their tools)
- ✓Training videos: YouTube electrical education channels
Where Paid Apps Are Worth It
- ✓Project management: Scheduling, dispatching, and CRM features that save hours per week
- ✓Estimating software: Accurate bids with labor databases directly improve profitability
- ✓Photo documentation: Team-wide photo management with GPS and time stamps
- ✓Blueprint viewers: Collaborative markup and version control for large projects
- ✓Comprehensive exam prep: Full question banks with detailed explanations
ROI Calculation for Paid Apps
Before dismissing a paid app, consider the math. If a $50/month project management tool saves you 2 hours per week of administrative work, and your time is worth $75/hour, that is $600/month in recovered billable time for a $50 investment. The same logic applies to estimating software: if better estimates help you win just one additional job per quarter, the software has paid for itself many times over.

Frequently Asked Questions
What is the best all-in-one app for electricians?
Ampora is the closest thing to an all-in-one electrical app. It combines AI-powered NEC code reference, multiple electrical calculators (voltage drop, wire sizing, conduit fill, box fill), and AI troubleshooting in a single free app. For business operations (scheduling, invoicing), you will still need a separate project management tool.
Are electrical apps accurate enough to rely on for code compliance?
Reputable electrical apps that reference the NEC directly are highly accurate. Apps like Ampora cite specific code sections so you can verify every answer. That said, apps are tools to assist your professional judgment, not replace it. Always confirm critical decisions against the actual code text, and remember that the AHJ (Authority Having Jurisdiction) has the final say on code interpretation in your area.
Do I need cell service for electrical apps to work on job sites?
It depends on the app. Many calculation tools work offline since the formulas and tables are stored locally. Ampora offers offline access for core features. Cloud-based apps (project management, blueprint viewers) typically require at least periodic connectivity, though most allow you to download content for offline viewing. Always pre-download what you need before heading to a site with poor reception.
Can AI apps really help with electrical troubleshooting?
Yes, AI apps that are trained on electrical systems and NEC code can provide structured troubleshooting workflows. Describe the symptoms (intermittent GFCI trips, breaker nuisance tripping, voltage fluctuations) and an app like Ampora will suggest a logical diagnostic sequence based on the most common causes. AI troubleshooting works best as a thinking partner that ensures you do not skip steps — not as a replacement for hands-on diagnostic skills with a multimeter.
How much should an electrician expect to spend on apps per month?
A solo electrician can build a solid app toolkit for $0-50/month. Ampora (free) handles code reference and calculations. A basic task manager (free) handles scheduling. Your distributor's app (free) handles ordering. If you add CompanyCam ($19/month) and a simple invoicing app ($15-30/month), you are fully equipped for under $50/month. Larger shops running Jobber or ServiceTitan will spend $50-300/month but should easily recoup that in efficiency gains.
Should apprentices use apps or learn from the physical codebook first?
Both. Learning to navigate the physical NEC codebook is an essential skill for the journeyman exam and for understanding how the code is organized. But there is no reason not to use apps as a supplementary tool. Apps like Ampora actually help apprentices learn faster by providing explanations alongside code references — something a raw codebook does not do.
What about Android? Are these apps available on both platforms?
Availability varies by app. Project management tools (Jobber, ServiceTitan), blueprint viewers (PlanGrid, Procore), and photo apps (CompanyCam) are generally available on both iOS and Android. Some specialized electrical apps are iOS-only or Android-only. Ampora is currently available on iOS with plans for future expansion. Always check your platform's app store for availability.
