### 1/5 — Ads

*2018-05-28*

Purchased the app to get the full option and remove the ads. All I got was the all the options and a ton more ads. In fact I get an advertisement even 3 seconds. Total waste of money. DON’T BUY THIS APP!

### 1/5 — No good don’t waste your time

*2017-10-16*

Keeps freezing, will not allow you to do the picket layout

### 1/5 — Not free

*2016-02-27*

Worthless app. You need to buy most of the features. Operated fine but deceiving

### 1/5 — Go

*2016-02-26*

Crap

### 2/5 — Don't waste your time. Can't change the units so inches only

*2015-09-20, version 2.0*

So extremely poor that you can't do a basic setting like choose your units. 

While it has a conversion calculator just to tell you inches for millimetres. That is just not the same. 

Also as others have said ads are introduced so poorly. 

Just a very very poor app.

### 1/5 — No good

*2015-08-23*

Crashes every time I hit the equals sign

### 1/5 — Waste of time

*2015-08-22, version 2.0*

Says its free but isn't. Only works with imperial not metric. Not worth the 1star!

### 5/5 — Accurate builder

*2015-07-25*

Nice construction app keep it up

### 4/5 — Best builder calc

*2015-07-23*

Very useful and working perfectly.

### 5/5 — Most Useful App

*2015-07-23*

I like this app. Its very useful for me. Now I can complete my calculation work faster than before.
