I just don't know what is good or bad. Seems convenient. But it is beyond my grssp and I have four college degrees, hustt not iin anything about medicing.

I'm not sure what your supposed to put in the fields, but the way it is described, if you have an apple watch, the app will tell you your qt interval when you do an ecg. What a waste of time and money.
