The app is incredibly useful. But is there any way you could add in Copper, Cast Iron, Concrete and Stainless Steel for different material types? In my neck of the woods, we deal with each of these different material types as well as the ones you have already. If you could get that going, this app would be my go-to. Hands down

Thank you! Yes agreed, it's important to know how to use the slide rule and not blindly using this app.

The specific emission constant for Iridium is incorrect. In Canada we use 480mR/hr not 520 or 590 like in the settings. I have emailed asking to have it fixed with no reply. It is a big difference in value and can alter our times quite significantly. Hopefully you can change it.

Can't remember receiving this email, otherwise I would have answered surely. When did you send it? Can you send that info again? Beside that, the values in the app are "H/hr/Ci @ 1foot", your value is for meter distance isn't it? in that case, 5.2 is the value to use for you (5.2 R/hr/Ci @ 1foot eq. to 483 mR/hr/Ci @ 1 meter)
