You need help with your app. There is no PDF to reference. Not reliable
How you guys can at least give the pdf for reference? Just need a pdf before my book comes in the mail. Not very happy with the information not matching up with the book reference. I can buy a better calculator/ AI system to provide me with the answers. I just aspected to be able to see the PDF , front to back when I bout this app. That’s what your website stated, but I don’t see a pdf of the reference book for Eletrical reference!!!!!!

App does not work as advertised
It has the usual solid, key information that the Ugly’s book has, however the app functionality is terrible in three key respects. One, the search function is so basic that it’s almost completely useless. NEC article number references won’t show up in search results, as well as any number of other basic key words and table titles. A pdf document is more searchable, never mind that a book index would contain more “searchable”information. Two, the bookmarks function doesn’t work at all...if I bookmark a page, when I go back to the bookmark... it takes me to the wrong page every time, even though the title of the bookmark is correct. It’s very frustrating!...Especially for something that is not free. And three, sometimes when I scroll through a section, the app will ”glitch” and send me to a completely different section with no way to get back to the section that I was originally looking at without going back through the menu titles and subsections and re-selecting my original page. I’m not sure why this app lacks the basic functionality that it itself indicates that it is capable of handling. My version utilizes the latest update. What’s the point of buying this app if it doesn’t even work as advertised. I don’t know that I would buy the app if I could go back...it’s failure to work as advertised makes it a hard sell over just getting the book.

Helpful to apprentices and even journeyman
I’m an apprentice electrician, I used to have the actual uglys book, but with the app I can access information alot quicker. Especially at a job site, where time is money. A journeyman who I was working with told me to get the app instead because if I don’t have the book with me at work, and I really need to know something, then I have to go on google which takes FOREVER to get factual information. Versus on my phone, I’m going to have my phone with me where ever I go. Therefore I have uglys references with me 24/7. Sometimes I read it when I’m not at work because I constantly want to learn new information. It’s definitely worth the money!
