PsyCalc®, the number one desktop psychrometric calculator for over 20 years, is now available for iPhone and iPad. Its intuitive interface, flexibility and wide operating range makes it the tool of choice for tens of thousands of professionals worldwide. The rigorous calculation engine driving PsyCalc® is recognized by many engineers as the gold standard.
PsyCalc® includes screens for finding properties of a point, mixing two air streams, finding process energies between two points and setting your screen defaults.
PsyCalc® operates in I-P (inch-pound or English) units or SI (System International or metric) units. Input and output values can be set to different units providing an easy means to make conversions.
PsyCalc® is immediate. Make a change to the inputs and the outputs are updated immediately. There is no calculate button, all values are always up-to-date and valid.
Numeric inputs are entered via a numeric keypad.

Ratings and Reviews
An absolute classic... finally on the iPhone
PsyCalc running under Windows has been a long-time standby for me. It's always been quick, accurate, versatile, easy to use and comprehensive without being overwhelming. In 15 years, I've never seen anything that can touch it for either practical everyday utility or impressive accuracy.
Now that I have PsyCalc on my iPhone, there's one less reason for me to have to boot Windows on my Mac. That saves me time, not to mention the fact that, as an iPhone app, PsyCalc now goes with me everywhere: building inspections, HVAC system diagnostic visits, water damage investigations, thermal imaging investigations of building exteriors, client meetings, overseas investigations, secure facilities in which I cannot boot my laptop... the works.
For those who've been using PsyCalc for many years, you'll find it the same steady, straightforward and reliable performer it's always been on the PC.
For those who have always used only a Mac and never had access to it before, you'll find PsyCalc a real delight to use. On the PC it's always been justifiably legendary for it's Mac-like ease of use, and the iPhone/iPad version lives up to that excellent and hard-won reputation.
I've used the PC app for years, so was happy to see it show up in the app store. Nifty interface for a sophisticated app makes it quick and easy to use. What makes it special, though, is that the app is a powerful program with capabilities far beyond other programs. For me, I need to calculate air properties at temperatures in ovens of up to 500 F, and this app can do it. Most apps are for HVAC, and so only work for typical room temperatures. The clean, simple interface is a bonus -- for the first version out of the gate, it has a polished feel that exceeds expectations. Well done.
A really excellent resource.
I purchased this app because I couldn't find a good way to get good thermodynamic information that I needed for doing drying calculations. There are many excellent features, and when I had a question, the author was back to me the next day with an answer. If you need this kind of data...this is the program for you!
