PsyCalc, the number one desktop psychrometric calculator for over 15 years, is now available for iPhone and iPad. PsyCalc's 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's results 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.

All of PsyCalc's functions operate in I-P (inch-pound or English) units or SI (System International or metric) units. Plus the input and output values can be set to different units providing an easy means to make conversions.

All of PsyCalc's functions operate as changes are made on the screen. There is no calculate button, all values are always up-to-date and valid.

Numeric inputs are entered via a numeric keypad.
