- 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!

- Interactive searchable Uglys App!

I originally gave this app 4 stars when it first came out but stated it needed a lot of functionality upgrades but has since then added everything I said was wrong with it. Now with pinch to zoom, completely searchable topics and text, and instructional videos such as in the conduit bending section, and pdf versions of the newest Ugly’s version, this app is as good as having the hard copy of the book in your hands at all times, but quicker for topics look up!!

- Really good

I really like the calculator function on here. You can put in all of the values and you don’t need to memorize the equations when you do it. I like the ugly book for a study reference still, but I love this app for when I’m actually doing work and need an answer now.

- Don’t like the new version

This went from my go to reference to a source of frustration. With the last update all my old bookmarks had to be replaced because they no longer sent me to the right reference. When I bookmark a chart it places the bookmark on the section not that actual chart like it would in the previous version. I’m finding the information just not as easily as I did before. I also have to be careful that I am on the right reference where before I clicked a bookmark and I was instantly on the reference I wanted.

- Good, but needs better offline usability

I find the book very useful, and I find it even better to have it right on my phone. The calculators are handy and I use the conduit bending section a fair amount. I’d give five stars if all of the text and diagrams from the book were available offline. It would be nice if you could download everything using wifi and then have it available without using data or needing good service. But I can always go get the book.

- This is worth its weight in gold

As a working electrician, I find this to be the most helpful of all the electrical apps on the market. It’s easily as useful as the actual book and the calculators in the app take away some of the math one normally must do on the job site.

- The Ugly Book has been my go to for years!

As a contractor, I have worn out several physical copies of Ugly’s Electrical Reference. Now having it easily searchable and always at my fingertips has increased our efficiency. This app is superb!

- Quick Check

Let’s face it, the load and pressure in the electrical business is hard enough at times. With all that we have to know and remember is madness on some projects. This app really is the ‘Let’s make sure!’

- Amazing!

Just as easy as having your Ugly’s book in your back pocket at all times. A great app with an easy search of topics and info that your seeking immediately.

- Great app only 1 problem I would like to see get fixed

Really good app the only problem I would like to see fixed is I wish you could just type in key words and pull up the sections

- Worth the $

Anytime I forget a rule or don’t know something I can find it on my phone. The 1 thing that is always with me. Can’t beat a quality app.

- Can beat it

It’s super easy to find what you are looking for. Has pretty much everything you need to figure out the job.

- Nice and quick way to access Ugly App

Nice way to carry app on phone. Wish there was a better/quicker way to access certain sections, but once you spend time with this you get the hang of it.

- Very handy App

Very handy when speaking to a customer and you can show them the requirements (motor size, wires size, etc.) right there in your phone or tablet screen.

- Great resource.

I use this app almost daily for checking power and cabling, this is an awesome resource to not carrying around the small spiral bound and easier to navigate!

- In the trade

I have no Audio in my pipe bending tutorials, it wasn’t always this way. I was wondering if anyone else was experiencing these issues?? Other then that this app is very useful. I’m waiting in a response from the app developer. If you’re in the trade I would recommend.

- Easy to use

Great interface, comes in handy more often than not

- Well worth it.

We all know what we know. But there were too many times I forgot stuff; due to time constraints. This books is a great reminder of stuff & over a broad range of topics.

- Ugly is beautiful

Quick useful information right at your fingertips. I highly recommend this app!

- Great App!

Very handy, I don’t need to lug my hard copy of Ugly’s around with me on jobs. Nicely laid out, easy to find info, and it updates automatically...

- Nice

Comes in handy for things you may forget from time to time.

- Not the book.

Was hoping to have all the information the book has on this app but it does not. Will buy book instead.

- Helpful App

Sure beats carrying a book around. Comes in very handy for verification of things I don’t have memorized.

- Awesome App

This app is great because now I don’t have to keep up with my Ugly’s Book because it is always with me.

- Great pocket guide

Always used your paper guides and now using your app allows me to not forget to have it on me.

- Great app

I’m only here to get rid of the notification to review it every time I open the app.

- Perfect!

This thing is as handy as a back pocket (and fits perfectly in one also).

- Awesome

Everything in the book and some!


This is where I turn to EVERY TIME I need to check or double check anything- SUPER EASY to use

- Video’s won’t play on IPhone 11

The app is great and supremely useful. However the conduit bending videos don’t seem to work.

- Great App!

I love this app, I’m a maintenance Technician and I use this app a lot when I need to reference back to drawings and schematics

- Save your money

There are a couple of better apps out there and less expensive. Don’t get me wrong the are a couple of good features but I’m not sure if the price is worth it . Disappointed in some of the calculation features and the bending conduit portion.

- The best

I love this app just everything that you need in the field...

- Love it

Use the app all the time. One of the best ones I have purchased!

- Very helpful

Works great for quick reference and calculations

- Excellent quality

Please get this app..I used all the time and it's like a Bible for electrician people

- Amazing

This app is awesome has all the info u need a must have

- Awesome!

A must have for any electrician! Especially helpful for those new to the trade!

- Poorly thought out and limited info

Not at all like the actual Ugly's book. Very limited and hard to find information. Not something I’ll use often as an electrician. Can’t even find conductor ampacity!

- Fire Alarm

Somebody could suggest me any application like this one for Fire Alarm Detection.

- Fine

Only reviewing so the app will stop asking me to review it.

- Good. Other than constant prompt for review!!!!

Title says it all.

- Calculation portion of app does not work

The calculation portion of this app is correct. When finding kw or hp of a load you get numbers that are way off

- Amazing App

This version is really useful !!!! Thanks for all the updates released

- Annoying pop up

Annoying pop up until reviewed

- Awesome App

Great app, easy to use. Use this app often at work.

This app has some decimal place inaccuracies in their calculations. E mailed them to let them know, no response, no fix

- Great for toolbox

Awesome accessibility for an already awesome quick reference guide.

- Electrician

Just an awesome experience

- Nope do not buy

Only writing review because when I finally use it, it asks me every..single...time to. Bookmarks erase. Just really do not care for the app.

- Like’s in there

Good ol reliable Ugly’s. The interface could use a lot of work. It’s not elegant at all.

- App not opening

Every time I try to open my UGLY’S app it closes. I need it to open. I use it a lot. Feeling cheated. Please respond immediately. Thank you.

- Writing a review

I’m writing a review so it will stop asking me to write a review. Otherwise helpful app

Very easy to use.

Needs update for iPhone X screen.

Great for a quick conduit bending refresher.

Can’t search by words. No where near as good as hard copy!

- Awesome

Very Helpful

- Great

Awesome app. Really comes in handy.

Awesome app for electricians

- Not worth $

Can I have my money back?


I will change to 5 star as soon as it works as it should

- Great

Great reference

- I have the 2017 version

Is the 2020 version free or just a trial version?

- Love it

Great app

- Great app

Great app

- Ugly’s

Great resource.

- Ok


- Can't subscribe

I subscribed. When I click nec updates it says I need a subscription when I click subscribe it tells me I already subscribed.

- Not good!

Not the book just a sample👎🏼👎🏼

- Great


- Good


- A step in the right direction

They have begun updating app. Still not the most user friendly but much more improvement over initial release. Developer seems to be addressing concerns for improvement of overall app. Hopefully with continued updates, app will become the UGLY'S that I've trusted and have gone to for over 20 years.

- THIEFS!! They took the money but no help with subscription

I needed this app for a new career path I started. The trial was great so I decided to purchase a subscription. They processed my payment through iTunes and took the money but the app doesn't recognize my subscription. Know I am in an endless loop to try to get this working or to get a refund. The developer blames Apple and Apple blames the developer. I don't even care now. Just give me my money back. Thiefs.

- Major Glitch

After I received the email saying that the subscription plan was dropped and that you could purchase the app once and "own it forever," I figured I'd go ahead and buy it. Well, here I am, 10 days after my purchase and when I open the app I'm greeted with the message that my trial period has ended and that I need to purchase a subscription to unlock the content. Seriously?!

- Doesnt work

After reading these reviews, I was hesitant. I went to the Uglys site and was reasssured by their forthright explanation of the changes made to the app and they confirmed that it was a one time payment. OK, perhaps all the prior reviews are just bad experiences. Purchased app. Installed, and the app gave a brief tutorial on how to navigate through it. It then crashed. Now it doesnt work at all. Shows splash screen for a moment then quits. I guess "I hate it" for 1 star is a little harsh, as opposed to "don't like", but for $13, it better do more than nothing. I have requested a refund from the app store. I hope the app developer is paying attention to these reviews.

- Great App

Has everything you need and pretty handy.

- Cut off sentences

Has a lot of helpful information. My main concern is that a good portion of the text is cut off, sometimes to the point of missing a couple words, and no way to move the screen over, or soom out to read it.

- Close but....

I’ve been waiting for this app for a long time but the very first calculation that I tried ended up with an answer that was 2 decimal points off. I tried to calculate amps when I know watts, voltage, and power factor. The app gave me an answer of 738 amps when it should have been 7.38 amps.

- Poor customer service

Purchased the app and once my trial period expired it said that I had to pay another 10 bucks. Tried emailing support and that's been about a month ago and still no word from them

- Great App

Excellent resource!

- Total crap ripoff

I bought the app for $9.99 3 weeks ago. Now it says I have to subscribe for another $9.99. Not gonna happen. If you want to get screwed out of your money, go ahead and download this app.

- They need to do better!

It's basically the ugly book with calculators. There is better pipe bending apps and electrical apps out there. You could just buy the ulgy book for a one time price. Then download other free electrical apps. Ibew 614 member submitted.

- Not worth $10

Too many apps out there offer free electrical material, calculations, & formulas without having to pay $10! Drop the subscription fee & offer the app for FREE.

- Tammy

Just bought this app and it crashes before opening

- Out of Date. Overpriced. Many errors. 👎🏼

Out of Date. Overpriced. Many errors. 👎🏼

- How to look smart 101

Bring up voltage drop calculator when it’s in question, select the easy to understand drop downs and quickly figure wire sizes needed! That’s just one way, I like to review the changes of code from time to time and see how that affects my day. It’s very short reading and easy to understand. Electricians best friend right here

- Uglys user

Good app for electricians and apprentices! Although I wosh it had more in depth NEC code topics like heights for outlets in certain locations etc. and stuff like that, but otherwise its a good reveiw tool!

- The Ampacity Calcualator is a Joke

So I thought by reading the reviews that this App would be the best out there....I was mistaken. The “Simple Ampacity Calculator” as it’s called is literally so simple that it’s useless. Instead of you being able to use actual Wire Insulation ratings on everyday conductors it only gives you a 30 and 40 Degree Celsius rating choice ??? That’s not even practical as we don’t live in Antarctica. Why can’t they just give you a simple option to select your conductor insulation rating and then select your De rating Temp value ie. 90 or 75 degree Celsius like every other free app out there ? and the code book mind also only goes up to 4/0 wire Gauge!!! Not everyone does residential work every day that uses this app and honestly if a licensed residential electrician needs this app for residential aside for the Ampacity calculator then imo they shouldn’t be working on their own....that’s a seriously massive oversight or honestly just neglect. For a name like Uglies, while some of the other information is nice....this app is getting Ugly for me.

- Stop asking for review.

Every time I open the app it asks me if I like it and then if I want to leave a review. That means two pop ups before I can use the app I paid for.This is very annoying and distracting. Other than that it does what I expected.
