Not good at all!!
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
Response from developer
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.
Hh
.99 was way too much !! Nothing I need here !!!
Good for a quick reference
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
FINALLY!
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.
