Hey PH 👋 I'm Arun, the solo founder behind VoltExam.
I built this because I kept hearing the same thing from tradespeople: the exam prep options out there were either overpriced, generic, or built for students — not for someone who works with their hands all day and needs to pass a licensing exam fast.
So I built 42 trade-specific apps: electricians studying the NEC, crane operators prepping for NCCCO, CDL drivers tackling hazmat endorsements, HVAC techs, plumbers, welders, and 36 more trades.
Each app has real practice questions, trade-specific calculators (voltage drop, load charts, refrigerant charge), and free cheat sheets. Web + iOS + Android. Start free for 3 days — no credit card needed.
One founder. 42 apps. Built for the people who build everything else.
Happy to answer any questions 🙌
