I can not find ampacity tables or conduit fill calculator along with most other things I used this app for. Hopefully it gets fixed soon it was a great tool to have on the go. ### 2/5 — Hard to navigate *2026-07-20, version 1.9.0* I’m sure this app has a ton of information just like the book - but the navigation is absurdly difficult to get to anything and it takes longer than going and finding a paper copy or code book to reference! Worst app for usability I have ever used ### 5/5 — Great product *2026-07-19, version 1.9.0* Really makes electric work so much easier ### 2/5 — App is fine *2026-06-17, version 1.8.9* Wouldn’t stop asking for reviews when I was trying to quickly look stuff up. Never left a review For an app before but they pestered me to this point. ### 1/5 — Update pulled features 🤯 *2026-06-09, version 1.8.9* The app used to be good, then they pulled features we all used. Where did table 310.16 go????? ### 1/5 — Newest update *2026-05-28, version 1.8.9* This app was great till their last update now 90% of what I used it for is missing and no way to access it anymore ### 1/5 — They deleted a lot of what you need. Not worth having anymore *2026-05-17, version 1.8.9* They updated the app and deleted several things I used, like the wire capacity charts and several others. What is the point of having an electrical reference app that does not address amperage ratings of conductors. Don’t buy it, ### 5/5 — Great, one suggestion. *2026-05-12, version 1.8.9* I like this a lot. Use it often. I have a hard time sometimes seeing the smaller pages that come up (yes I wear glasses) but still think it would be beneficial to make the pages zoomable? Thank you! ### 1/5 — this app is basically unusable *2026-05-09, version 1.8.9* this app has so much potential but the search function is garbage and it takes to long to find the basic tables and information that i will just walk to my truck to get my ugly book. when i eventually do find what i am looking for and bookmark it for later it gets deleted when the app updates. it would be nice to just have a pdf copy of the ugly book to accompany this app so it would actually be usable. ## Frequently asked questions about Ugly's Electrical References ### What does the Ugly's Electrical References app do?
