Based on the lack of response to comments here, and updates (last update August 2012) I would say they aren't interested. If there was a link from the app for feedback I would use it. A disclaimer EVERY Time I launch the app. Data that is wrong when you change to "hg and put in a positive number. I could go on. DuPont, are you listening?
Crashes! I just downloaded this app, and it seems to crash everytime I use the info tab. Seems to be pretty decent if the freon info tab would work. Please fix
Missing refrigerants Pretty useful, but doesn't have R401-A. Still learning about this stuff so I don't know yet if it has any other refrigerants missing
