HVAC Refrigerant Charge
1. Perform superheat refrigerant charge calculations for 75 different refrigerants. Input the indoor wet-bulb and outdoor dry-bulb temps. to get the target superheat temperature. Then, specify the suction line temperature and pressure to get the actual superheat temperature. The difference tells you whether to charge or not.
2. Perform subcool refrigerant charge calculations for 75 different refrigerants. Input the indoor wet-bulb and outdoor dry-bulb temps. to get the target subcool temperature. Then, specify the liquid line temperature and pressure to get the actual subcool temperature. The difference tells you whether to charge or not.
3. Use an interactive slider control to increase or decrease all values and immediately observe calculated results. Also, the slider control allows for "incremental" changes so you can ever-so-slightly change values to observe newly calculated results.
4. Specify atmospheric pressure (other than standard 14.7 psi) so that calculated pressures are adjusted for high elevations like those in Denver and elsewhere.
5. Customize input types so that you can specify manufacturer-specified target superheat/subcool or input indoor dry-bulb/indoor relative humidity in place of indoor wet-bulb temperature.
6. Send an email of all inputs and results with custom message
7. Display input and result values in either English or Metric units
8. Change the color scheme of the app so that it can easily be viewed outdoors in direct sunlight
9. It is "Bluetooth aware", meaning that it will connect via Bluetooth to those PT gauges that are also Bluetooth enabled. This will allow the automatic transfer of temperature/pressure information from those gauges to the HVAC Refrigerant Charge app.

Very bad apps. It is not working with android. I've lost my money. Please don't try it.
Good calculations for superheat targets; but it is incorrect in calculating actual superheat because it is using bubble point instead of dew point for 407c. This could easily be corrected. In the meantime it's recommendations will lead to overcharging equipment.
Allows you to know what the supeheat and subcooling is supposed to be under various indoor and outdoor loads for determine proper charge of systems. Input your readings and ypu know exactly were you should be. Always take in account your temp probs and clamps error facters.
It should be able to select the type of temperature unit and the type of pressure unit independently. In my case I work in PSI and Celsius, and I'm not able to work comfortably not having the choice.
Downloaded it to use on a recent job with 407c couldn't check the sub-cooling because it uses bubble p/t chart for both
Much of my work requires performing refrigerant charge calcs in the field. This app is perfect for doing it automatically. It has every refrigerant under the sun, and it allows me to email results back to the office.
This item is awesome!!! I love it!
This app used to work on my iPhone. it was the best charging app. But I got a Pixel 3 and now it won't even open. Developer doesn't seem to care.
