The 7 best apps for electricians in 2025 (that actually save you time)
The days of carrying a battered NEC codebook and a clipboard into every crawlspace are over. In 2025, the most valuable tool in your truck isn't your multimeter—it's your smartphone.
But with thousands of "construction" apps on the market, which ones actually handle the grit of daily electrical work? We've tested the top contenders to bring you this list of essential apps for calculations, project management, and getting paid.
1. The code bible: Ugly's Electrical References
Best for: Quick code lookups and safety standards.
Price: ~$12.99 (One-time)
If you've been in the trade for more than a week, you know "Ugly's." The app version of this legendary reference book is a must-have. It puts mathematical formulas, NEMA wiring configurations, and conduit fill calculations right in your pocket. Unlike the physical book, the app has interactive calculators that do the math for you.
Key Feature: Interactive voltage drop calculators that save you from scribbling on drywall.
2. The math whiz: Master Electrician Reference (MER)
Best for: Complex electrical calculations.
Price: ~$9.99
When you need to perform heavy-duty calculations that go beyond simple Ohm's law, MER is the industry standard. It handles circuit parameters, transformers, and intricate wire sizing with ease. It's significantly faster than using a standard calculator and reduces the "human error" factor on expensive material orders.
3. The proof of work: SiteSignOff
Best for: Preventing disputes and getting paid instantly.
Price: $9.99/month
Most apps focus on doing the work, but SiteSignOff focuses on proving you did it so you get paid. It solves the classic "he-said-she-said" problem by allowing you to snap before-and-after photos, stamp them with GPS/time data, and collect a digital signature from the client immediately.
Key Feature: Offline Mode. It works perfectly in basements or concrete bunkers where you have zero signal, syncing your invoices the moment you step outside.
4. The project manager: Fieldwire
Best for: Large commercial jobs and blueprint management.
Price: Free tier available; Pro starts at $29/user/mo
If you are running a crew on a large commercial site, Fieldwire is the heavy hitter you need. It allows you to view blueprints on your phone (zooming in without losing quality) and assign tasks to specific apprentices. If you find a mistake in the wiring plan, you can mark it up on the app and everyone's plans update instantly.
5. The conduit bender: QuickBend
Best for: Precision conduit bending.
Price: ~$4.99
QuickBend is one of those simple, brilliant tools that pays for itself in saved copper. You simply enter the type of bend you need (offset, saddle, three-point) and the obstruction dimensions, and it tells you exactly where to mark your pipe. It supports almost every bender on the market.
6. The accountant: QuickBooks Online
Best for: General bookkeeping and taxes.
Price: Varies by plan
While not specific to electricians, it integrates with almost every other tool on this list (including SiteSignOff). You need a central hub for your expenses, mileage tracking, and tax prep. The mobile app is surprisingly robust, letting you photograph receipts so you don't end up with a shoebox full of thermal paper at the end of the year.
7. The scanner: CamScanner
Best for: Digitizing paper documents.
Price: Free (Freemium)
Until the whole world goes digital, you will still deal with paper permits, napkin sketches, and supplier receipts. CamScanner turns your phone camera into a high-res document scanner, automatically cropping and brightening images so they look like professional PDFs rather than blurry photos.
