There really isn’t much more than what i saw on the 2011 light version vs. this that warrants the price. I thought the “what’s new for 2017 “ would be a interactive theme as opposed to just pointing out the updated articles. Just 1 example of my disappointment . But as I stated I could’ve and should’ve done more research, not all the developers fault. **Developer response:** Sorry I did not get back to you sooner. The paid version contains over 7 times as many articles as the free Lite version. The Lite version is free so you can try-before-you-buy. The Lite version includes a listing of all the articles and topics of the paid version so you know what you get before you buy. If you have suggestions for improvements or ideas for what we can do better, please use the "Contact Us" menu item in the app. We appreciate all feedback. ### 1/5 — MER 2017 *2019-01-06* I'm trying To figure this out. But it's not letting me get anywhere that I want to be. So if this is as far as it is going to let me go I'll never buy anything from you again. **Developer response:** I'm sorry you are having trouble with the app. Contact me directly (there is a Contract Us menu item in the app) and I'll be happy to help you. ### 1/5 — Problems from the start *2018-05-17* Not happy spending money on this when the table of contents overlap and it becomes not legible. How do I get my money back? **Developer response:** I'm sorry you are having trouble with the app. Contact me directly (there is a Contract Us menu item in the app) and I'll be happy to help you. Please include a screenshot so I can see what is wrong. ### 1/5 — Not a useful app *2017-12-25* Not much information . How can I get a refund? ### 2/5 — Conduit fill *2024-01-04* How do you change the conduit type in the conduit fill menu? It’s set for emt. ### 2/5 — What’s the point *2023-10-31* I guess I misunderstood what this app does. It’s just a bunch of PDFs of what my codebook or uglies will show, but there are no calculations. Ie. Does not even calculate conduit fill. Am I missing something? ### 2/5 — It’s like the NEC book but in PDF *2021-04-10* Most of the article copyrighted 2016... and I don’t see calculation tool for sizing or anything **Developer response:** This app contains some 2017 NEC tables and they are copyrighted 2016 by NFPA and we reproduce them in the app with permission. This is only a small part of the app. ### 4/5 — Its got almost everything you need *2020-09-19* I took one star out cause your table for voltage drop wasn't matching with the right answer for one of the questions in your quiz app. I think it was question 75. It goes something like, whats the length of wire for 12 awg with 20 a breaker at 3% drop. Table clearly shows 25’ but quiz app says its the wrong answer. So idk what other things are inaccurate here. ### 5/5 — Updates *2026-03-31* When are you going to update to the 2020 or 2023 codes? ## Most praised reviews (9 highest-rated) ### 5/5 — Excellent Electrical Reference App *2026-02-15, version 2.0.8* This app is extremely helpful for electrical code references and field calculations. It’s organized, easy to use, and reliable when you need quick answers on site. A great tool for apprentices, journeymen, and those preparing for their Master exam. Definitely a valuable addition to your toolbox. ### 5/5 — Master Electrician *2025-02-25* Best app for quick reference, thumbs up. ### 5/5 — Best Electrical Reference App!! *2023-05-07* This is probably the best overall app for electrical references for any on the job Electrician, Engineer, Mechanic, etc that there is out there.
