HVAC PT Chart

I use it multiple times per day out in the field. I like that it has so many refrigerants in the list and I can also email.

Exactly what I needed. Free app but wouldn't have minded paying for it. Gets the job done. Simple to use. Great all around app

This PT chart app is probably the best on iTunes because it has every refrigerant on the planet, but the interface could be better. On my iPhone the refrigerant selection window takes up half the screen. That leaves a lot less space to view the temps and pressures I need. You guys need to shrink down the refrigerant selection window so it is easier to use the buttons and slider. Also it would free up space to make the readout windows a little bigger so it's easier to see the numbers. Other than that the app works great and is pretty accurate. The info is good, it just needs a better presentation.
