I live this app!

### 5/5 — 2020 Update Needed

*2022-09-29*

Great and Useful app.!!! A code reference based on NEC. A guide to help you figure out the basic calculations. Just plug in the numbers.

### 4/5 — 2020/2023

*2022-09-24*

Will there be a new or updated app? 2020 or 2023?

### 5/5 — Great App. Hopefully they will make an Updated one

Great App. Hopefully they will make an Updated one

### 4/5 — Not working

*2020-11-17*

Just wanted to inform the designer that the app will not open with the latest updates. Follow up is required for continuous function. 

But I do love the app when functioning correctly.

### 3/5 — Good, but not as good as android version

*2020-08-27*

I used this app every day on Android, and thought they would both have the same function. It’s too bad they don’t. I’m really disappointed in the iOS version.

### 5/5 — What more can you ask for.

*2020-03-02*

It’s great and it’s free.  Quickly reference everything you need before you make the stock call.  Look smart on ever job.
we know where are not Einstein’s we need to double check.  Picture perfect planning you know the rest.

### 5/5 — Add motor and transformer info

*2019-10-16*

This app is really useful and definitely earns the 5 stars. However, I just switched over from android and I’m really missing the motor and transformer info that existed on the android version. Please add to the iOS version!

### 5/5 — Very well done

*2019-05-23*

I’m upgrading from EWP 2014. I’d like to see motor and transformer info. Hazardous space would be nice too. Not to be misread: this app is one of the best electrical apps available.

### 2/5 — Needs work

*2019-05-03*

The Android based app is way better. Can you make it identical
