Latest reviews of HVAC Psychrometric LT app for iPhone and iPad

Works great
I wanted an app that calculates Humidity ratio in metric. This does it simply, cleanly and with little effort. I can plug in my measurements and get my result right away without going to the charts. I can also check that my measurements are correct with the various input options. I will consider their other apps.
Nice app
I use this app to track mill conditions in the plant I manage. We spin cotton and polyester yarns and both temp and RH play a key role in processes running well.
Simple and inexpensive
This app is awesome for the price (99 cents). Works on both my iPhone and iPad and looks great. Also works for me up here in Denver where the air density is low. Great app.
