App Comparison: 2026
What to Look For in an Electrician Exam Prep App
NEC Edition Matters
Most states now test on NEC 2023, while others still use NEC 2020. Make sure the app you choose specifies which edition its questions are written for. Outdated questions can teach you rules that no longer apply on exam day.
Offline Access for Job Sites
Electricians study in the field, on job sites, and in areas with spotty signal. Full offline access — not just "limited offline" — is a must-have. You should be able to run practice sets without Wi-Fi.
One-Time vs. Subscription Pricing
A subscription app charges every month whether you're actively studying or not. Pocket Prep's Skilled Trades plan is $10.99/mo or $59.99/year — and that $59.99 recurs every year, while VoltExam's $59.99 is paid once. A one-time purchase means you own the app through your exam and beyond.
Calculator Tools
Load calculations and voltage drop problems appear on nearly every journeyman and master electrician exam. An app with a built-in Voltage Drop Calculator lets you practice the math the way you'll actually see it on the exam.
