Great app, my entire shop uses it. But the tolerances for what's a correct charge are a bit off. for subcool, only 1 degree off is all I'll allow. Would be nice if I could adjust what is considered a correct charge in settings, but that may just be me. Other then that, has all the refrigerants even 454B as it came out and works great.

I absolutely love this software, it is extremely extremely easy to use and I tell technicians and installers to download it so we don't have to worry about referencing a charge chart for superheat. I also LOVE that the interface changes the range and available number of temperature options and just doesn'taleays have the same values.. (i.e. if you select 50 degree indoor wetbulb, it only gives you 2 options for outdoor dry bulb 55 and 60 degrees) AND says to not charge at low temps, etc. LOVE IT

Great app 5 stars. But even with five stars there's always room for improvement. I'm an HVAC tech, an located in the deep south (New Orleans area) which equals high temperatures with high humidity. I have noticed on several occasions the highest dry bulb temperature I can select was 95 degrees it gets hotter than that here. Also when doing superheat, sometime I cannot set the proper wet bulb temperature that I actually have with the pressure that I have. I will have to raise the actually temper

Great resource. A little cumbersome to use sometimes, because looking up recommended superheat requires entering system values too. When ambient values change, you have to reenter all the parameters. A little annoying, but still workable. Overall the app is very helpful. Edit: used it again on my R22 system. Airflow is another great feature. You can really tune up the whole system with this app. Raising my rating from 4 to 5 stars. Hard to find this data elsewhere. Thanks a lot developers. Edited

Works great in the field when you don't have time to do all the calculations. Simple to use. Has lots of options for refrigerator.
