### 1/5 — Where are the calculators?

*2021-07-22*

The Ap says there are calculators.  There aren’t.  Only formulas.  The Ap is mostly just a bunch of cut and paste plagiarized charts.

### 4/5 — Not bad

*2019-07-13*

Not a bad app! I read reviews on being able to read it and not being able to zoom. I turned my phone sideways and it makes it bigger. You can also screenshot the image and then zoom that may be a little aggravating but it works.

### 3/5 — Guy Calculator

*2018-07-19*

I like this app I was just wondering what happened to the guy calculator that used to be on it??

### 2/5 — Really!?

*2017-11-02*

I bought this app then after I downloaded and opened it, it wasn’t compatible with iOS 11 update app please!!!!

### 5/5 — Update

*2017-10-23*

Need to update to run with ios11

### 1/5 — Update

*2017-10-13*

This is a great app. But is down till updated for ios11, still waiting!

### 4/5 — Useful, hopefully still relevant

*2017-01-05*

First off, you can zoom!! Tap on the image and it pops up in another page and is zoomable. Linework is changing so much some of the minimum approach things and such might be outdated. But I'm sure they are still practical, good app though from the looks of it

### 4/5 — Good App

*2014-09-05*

The items that are hard to see, try tapping on the right side of the screen, I did this and the page turned and then i was able to enlarge/zoom in to see with my "old man" eyes, without the eye"crutches" on. Give it a try

### 5/5 — App works great

*2014-02-16*

Really good app lots of useful info well thought out.  As for the small print all you have to do is tap on diagram and it opens up and you can expand to view close up.

### 1/5 — Lineman app

*2014-01-07*

It's a great idea, and looks like it's setup good, but like a lot of the other reviews state. It's almost impossible to read it, if you could zoom I would've given four or five stars
