### 1/5 — Not good at all!!

*2011-09-11, version 1.0*

So I bought this app thinking the contents may be useful in the field. What I got was alot of formulas with no reference on how to use them or what they mean. As I see it, if you know how to read the info in this app then you shouldn't need to use it. Worthless n should be free. Not $1.99

**Developer response:** We are sorry you are disappointed with our app. We have added a lot of content over the last 6 years and you are correct the content is for advanced HVAC professionals as well as HVAC engineers.

### 1/5 — Hh

*2010-10-23, version 0*

.99 was way too much !! Nothing I need here !!!

### 4/5 — Good for a quick reference

*2010-08-10, version 0*

This all does not calculate anything it is just a reference guide. It's a very good reference and rule of thumb guide with lots of useful equations. The only thing I would add is where the equations and data come from. It looks ASHRAE based but not sure if it is

### 5/5 — FINALLY!

*2010-06-16, version 0*

There seems to be an app for everything stupid, and these guys actually put together some incredibly useful resources with this one. HIGHLY RECOMMENDED, though because I run a building diagnostics firm I upgraded to the Pro version. Can't beat 99 cents though. Buy it.
