User reviews

Practical & well put together!

This is the most practical NEC reference apps I’ve seen for electricians. The NEC is massive and can be intimidating to navigate, especially for apprentices, but this app makes the code approachable, searchable, and extremely organized.
The quick reference tables alone are incredibly useful in the field — ampacity charts, conduit fill, grounding conductor sizing, voltage drop, motor tables, torque specs, wire color codes, and more are all easy to access in seconds. The search functionality also makes finding NEC topics and articles much faster than flipping through a large code book.
What really stands out is how clean and discoverable the interface is. Journeymen can use it as a fast field reference, while apprentices can use it as a learning tool to better understand the NEC and common electrical practices.
This app turns a complicated code book into something practical and usable every day on the job. Highly recommended for anyone in the electrical trade.
