Needs update for iPad

Psyclone is a useful app for psychrometric calculations and basically works very well.

Since, I would presume, this application was originally developed for smartphones, I understand the limitations of the display area. This comes into play when viewing the plots on the psychrometric style chart. My suggestion is that the program be expanded to provide a psychrometric chart that displays the standard scales and information found on all psychrometric charts: enthalpy, saturation temperature, dry bulb temperature, relative humidity, dew point, humidity ratio ect...

The second improvement I would suggest is to add the ability to email and print both the calculations and the plots on a full psychrometric chart.

I believe that The implementation of these suggestions in the next version would create a very powerful and useful application for engineers and anyone else that works with psychrometrics .
