Nice work Phoenix!!! ### 5/5 — Business Development Manager *2010-07-28, version 0* This app really simplifies psychrometric calculations.

Makes short work of determining grains, dew point, and dehumidifier performance. Best of all, I always have it with me on the job. ### 5/5 — Student *2010-07-10, version 0* This is a great app! Very useful for calculating dew point - love it! ## Most critical reviews (10 lowest-rated) ### 2/5 — Needs évaporation potential calculator *2010-10-19, version 0* It would be great if this app could calculate temperature And vapor pressure to give us EP. Thanks! ### 3/5 — good for technicians, limited value to engineers *2012-06-28, version 1.4* good and simple app for folks concerned with the limited application of drying operations. for broader engineering applications, look elsewhere. ### 3/5 — Nice *2011-06-08* Handy tool. Easy to use. Any chance of UK calculations? Ie, g/kg? ### 3/5 — Pretty good *2010-10-08, version 0* Good except it doesn't convert to vapor pressure which is a big problem for me. ### 3/5 — Need something more *2010-08-11, version 0* I have need of a Psychrometric Calculator that converts Wet Bulb, Dry Bulb and either Pressure or Altitude into Humidity using grains/lb as the unit. Any chance you could add that to your next rev? Otherwise it seems to work fine. ### 4/5 — Good app *2012-03-08, version 1.4* Very good app for quick calculations, but pints per day is wrong. I think they used the gallons per cubic foot instead of weight per gallon. Very helpful though. ### 4/5 — G.M. *2010-11-15, version 0* This app saves me a lot of time. It allows me to make drying decisions quickly. ### 5/5 — Simply the best *2026-03-26, version 1.7* I’ve worked in restoration going on 9 years and this little app still comes in handy despite being built into many restoration software programs. They’ve kept it simple and update it as needed. 5 stars all day long ### 5/5 — Great program *2020-02-11, version 1.7* I was doing some calcs on our FCC regenerator and wanted another way of getting water contents for air other than psychometric charts are calcs. Found this, did some spot checking and it seems dead on. Great little program, can’t believe there is only one review. ### 5/5 — Does what it says *2013-07-27, version 1.5* Does what it says ## Most praised reviews (7 highest-rated) ### 5/5 — 5 Star App for restoration tech's *2011-12-23, version 1.4* I give this App 5 stars!

Can you do it? ### 5/5 — Great calculator *2010-11-14, version 0* Great calculator and simple to use I would realy appreciate if you can display both dew point and gpp on the same page without having to change all the time .
