### 1/5 — Little Information, Way Overpriced! Bad Job.

*2013-09-04*

The screen shots show the entire app you are paying $2.99 for, so you can't say you were cheated. That's all there is: a very simple calculator of voltage drop in a wire, given gauge, length, and amp load, and a printed table that shows the physical size of a wire gauge (seldom useful: if you are using big wire sizes, you already know how much area to allow for the wire). THAT'S THE WHOLE APP.
This is WAY, WAY overpriced, for an app that is too simple for an electrician, and too much odd information for a DIYer. This is a Bad Job. The real ripoff is that I assumed that anything so expensive must have more value. Not true in this case.

### 1/5 — Over priced

*2009-03-14*

Missing base voltage, drop percentage, fail pass according NEMA specs.

### 2/5 — austrailia

*2009-01-12, version 0*

would be good if you warned people about it being american or you could make an update that would make it internationally friendly great idea tho

### 3/5 — Electrcal contractor

*2009-01-19*

Good but needs to include larger wire sizes.

### 4/5 — Pretty good

*2013-12-28, version 1.2*

This app is very good,
The display field runs into the menu bar on the iPhone, making it a bit confusing when first changing the settings but it does work.
Does exactly what it says.

### 5/5 — Very useful

*2022-01-03*

I have used this app many times and it is very helpful

### 5/5 — Great app

*2014-09-13*

Clear and correct! I use it every day

### 5/5 — Not seen in any other App

*2013-10-25*

It has a field to allow input of circular mils per Amp to evaluate PCB trace widths based on square mil cross-sectional area. The guys at Black Cat Systems were very responsive to this feature request. They had it up within days.

Great job!

### 5/5 — Wire calc
