Works great!
Easy to use and accurate. Use it every day.

Does not work. 72/46 is not -7.6 dew point. How to get refund is the ??
Don't buy
This app will give you false readings I can calculate better and more accurate than this app if you need one then go to Ashrae HVAC Psychrometeric chart apps and download that it will cost you $20.00 but you pay for what you get !!!!!!!!!! This app is crap DONT but this app.π
Now very Good
Answer Not really Good...
R&D Use
Four senior R&D execs in our company use it and have never had a problem in F or C. Easy conversion and more flexible than most other apps. There is a small error near 0degF and tiny inconsistencies near saturation but these would only be noticed by a scientist. Great app. Is it available for Excel?

Great app for mechanical engineering students
It's a very useful app when doing homework instead of looking
for the results in the psych charts and especially when it comes to
interpolation. I haven't run into any inaccuracies, yet. Also, I like
that I can calculate for different elevations and barometric
pressures. I highly recommend this app.

Beats using those cardboard psych calculators
I have one of those cardboard Vaisala psych calculators, kind of like a ductulator but for psych. calcs. Anyway, I've been using it for years and it was ok. Now, that I've downloaded this app, I much prefer this: it's quick, let's me specify a large # of input parameters, and instantly displays the results. Good stuff.
I also like the fact I can calculate for high elevations since I live in Denver.
Great work!!!

Works great out in the field for HVAC diagnostics
I am doing a lot of diagnostics these days with cooling coils, etc. I really need to do lots psych calcs to determine what the wet-bulb and relative humidity values are. This app is awesome in the field for doing this. Also, I like the mixed-air function for those more complicated jobs. Great work.
Great app but...
I've used this app many times in my hvac class and all the values are correct other than enthalpy. So be sure to compare that value to the actual chart because it is way off. I sent a thing to the developers so hopefully the issue can be resolved. The odd thing is that the value for enthalpy when using the mixed stream is correct.
