Must have for other stuff to but especially for conduit bending -- AdudeWhoReadstheBible, 2024-12-14 ### ***-- "Can’t zoom?" Text zoom and page zoom are two different things and this app needs the ability to zoom in especially with the “Symbols” page, e.g. -- monnijae, 2024-12-03 ### ***** "Great Reference Guide" Love the fact it contains NEC update from 2014-2023. Not to mention all the useful information. -- Seconds86, 2024-11-23 ### ***** "Must have" Great app glad I purchased it -- Hulsey HVAC, 2024-11-08 ### ****- "Android version better" Overall a useful app but when having to select your choices in the calculations the menu is dark and hard to see -- SparkyDave79, 2024-08-28 ### ***-- "Tables and charts" I find the app helpful. It covers a lot of detail. I wish I could put in specific article numbers and get that information on the app directly from the NEC book. I wish the tables and charts would allow me to zoom in versus having to take a snapshot photo of them to be able to zoom in. -- medicrn1212, 2024-08-15 ### *---- "Not worth it" Can’t find what is looking for not the same as the book -- kakahole20, 2024-07-19 ### ****- "I would’ve gave it 5 stars but" Great app to use but it will only be helpful if you already have some knowledge in the electrical field. Would have gave it 5 stars but it asks every time you open to rate it. Hopefully after clicking not sure for 2 years it will stop after writing a review? -- Scruffyatx, 2024-07-16 ### *---- "Asks to rate everytime app is opened" Dumb -- hawkamp, 2024-07-03 ### ***** "Great app" Great app to have a pocket reference -- ericcc1, 2024-06-20 ### *---- "Very disappointed, nothing like the book" I needed this for industrial wiring and general reference. I have the book and expected the app to be somewhat like the book but it's missing basically everything I have needed on the last several installs. I'm not a professional electrician but I work with control cabinets and such. -- Firebrand4, 2024-05-24 ### ***-- "App not working." Trying to use the offset calculator. The screen keeps loading and resetting barely allowing me enough time to type any calculations in. App worked fine up until this week. -- Iannn1999, 2024-05-24 ### *---- "not worth the space on my phone" this app is garbage …….the search option? haha forget about it… there is very little information for somebody who don’t know what they are doing. i would recommend a different reference this one is not good at all -- terror559, 2024-03-27 ### *---- "Pease fix" Please fix the dark scrolling menus in the calculators. -- ShortMag270, 2024-03-19 ### **--- "Lacks Bending Requirements" Doesn’t inform about shrinkage for 3-point saddle. Miss leading, ended up having to refer to real uglys cause it includes the correct info. Don’t think an electrician created this app. -- GucciMain35883, 2024-02-22 ### ***** "Great app" Love it -- Mzimmer28, 2024-01-28 ### ****- "Zoom" Love the app can you please implement a zoom function -- Ret taco, 2024-01-25 ### ***** "Very pleased with it" I was surprised on how much information was given it has help me with a lot and is a great resource for questions that I can get answered if I can’t get it from someone -- Nick V. 23, 2023-12-06 [View all Ugly's Electrical References reviews and detailed analytics on AppTail](https://apptail.io/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Ugly's Electrical References Store Rankings | Chart | Country | Category | Rank | |-------|---------|----------|------| | Top Paid | United States | Productivity | #3 | | Top Paid | Saudi Arabia | Productivity | #4 | | Top Paid | United States | Overall | #62 | | Top Paid | Saudi Arabia | Overall | #67 | | Top Paid | Canada | Productivity | #68 | | Top Paid | United Kingdom | Productivity | #101 | | Top Paid | Dominican Republic | Productivity | #130 | | Top Paid | Azerbaijan | Productivity | #172 | | Top Paid | Israel | Productivity | #203 | | Top Paid | Mexico | Productivity | #259 | | Top Paid | Colombia | Productivity | #275 | | Top Paid | Philippines | Productivity | #285 | | Top Paid | Ukraine | Productivity | #377 | | Top Paid | Peru | Productivity | #453 | | Top Paid | Pakistan | Productivity | #481 | | Top Paid | Kuwait | Productivity | #486 | | Top Paid | Ireland | Productivity | #491 | ## Ugly's Electrical References Discovered Keywords -
