### 5/5 — Great App!!

*2020-06-04*

This is a great simple to use app which works even better after being updated. You can scroll to infinity which makes it great for those multi section panels. You can type a number and it automatically jumps you to the color. It’s quick and easy for checking while on the job.

### 1/5 — Not applicable in Canada

*2018-05-30*

The phasing in the app is per American electrical code. Canadian code is red-black-blue.

### 1/5 — They need to update the app

*2017-11-03*

### 5/5 — Important.

### 1/5 — App was good

*2017-09-23*

This app won’t work with the new os 😡

### 2/5 — Colour code

*2016-01-21*

Ya can u change colour code to red,black,blue it would make more sense

### 1/5 — Colour code

*2015-09-26*

How about a Canadian version red black blue site looks like it can do both Canadian and U.S. 2 bucks down the drain

### 1/5 — Brutal colors

*2014-09-23*

Seriously black red blue?  Someone's apprentice had a touch of the downs

### 2/5 — Wire phasing is wrong!

*2013-07-04*

The 3 phase colour code is wrong....
Should be red, black, blue instead of black , red, blue.
Disappointing for such a simple app!

### 1/5 — Don't waste your money!

*2013-04-06*

This app is a waste of money and you can't edit it anything, no labels, no settings page for it, and it doesn't tell you what applications the colors apply to. Best advice buy 'Circuit colors', instead! Your welcome.
