    Bitzer refrigerant of pt chart, Dropbox for storing all those manuals and videos on equipment.

    PDF reader, to read those manuals on pesky equipment.

    I use the dupont PT calc and ibooks. PDF management is essential. Thats all I use my ipad for.. so my manuals don't take up all my cab space.

    My most used HVAC related app is HVAC Buddy, for target superheat and target evaporator temperature drop(aka Target Evaporator Exit Temperature).

    Search for ExactCharge Calculator 3.0 in iTunes.
    Back when I was using a PDA, I used ExactCharge all the time.
    I'd switch back to it from HVAC Buddy if you would add target evaporator exit temperature calculation to it...
    If more government is the answer, then it's a really stupid question.

    I am going to be doing an update to include some newer refrigerants like MO99 and R427A later this year so may go ahead and add the TEET into the calculator at that time.

    My new HVAC Flat Rate App has been keeping me kinda busy during the last 6 months.

    I brought it up in a couple of threads YEARS ago though.

    I know.

    I gave it a half a$$ed effort about 8 months ago. Tried to find or make a math formula for it but was unsuccessful.

    Seems we will need to input the chart and then pull averages out of it for 1 degree increments.

    Not unless someone has a formula for it and would like to share.

    I know it can be done though with the chart.
