### 1/5 — DONT PURCHASE

*2020-05-13, version 1.0*

They should have a negative rating minus x this app is a joke not complete provide little to No information. I’m insulting apps with one star by being forced to give a star rating. -10trash

### 1/5 — Useless

*2019-12-05, version 1.0*

App has hardly any content. Need a refund!

### 1/5 — Terrible

*2017-06-20, version 1.0*

Useless. Use websites instead of this app. They're free and this has no useful information.

### 1/5 — STOP! Still don't buy it!!!

*2017-05-03, version 1.0*

I thought after a year of bad reports they would've improved it! NOT.... very limited information, states SOME codes but doesn't go to them or allow you to go to them to read them. Useless..... Extremely disappointed and yes, I wish we could get our money back when when someone displays bad apps. Note to developer, listen to your critics and please improve app. Use the code book and display residential codes from foundation all the way through the house to the roof.  It can be a good app. If you displayed codes in meanings.

### 1/5 — Do not buy it

*2016-04-30, version 1.0*

It's a great book cover 
But Nothing in side of the book 

Refund my money !

### 1/5 — How can I get my money back?

*2015-05-19, version 1.0*

How can I get my money back? There is no information on this app.

### 1/5 — Unfinished app

*2015-02-23, version 1.0*

Barely usable. Only one of the four main sections looks done ( electrical codes). Information is very minimal compared to the real code book. Only found one calculator and I'm not sure it works. None of the code numbers are hyperlinked so you have to scroll down to see details. All in all it would be hardly useful as a free app. Paying $2.99. Is outrageous.
