Chickcharnie, I've received a reply from IB regarding your inquiry.
Me: FitDay advertises that FitDay PC tracks Blood Sugar and Blood Pressure here: PC Weight Loss and Diet Journal | FITDAY IT DOES NOT, as verified by members as well as one of our Moderators. Apparently someone got PC confused with Premium when they created the advertising page.
IB: Both products use “custom tracking” which will allow you to track blood sugar and blood pressure.
I know it's not what you wanted to hear and frankly I'm dumbfounded by this whole thing.
The only possible explanation is this, but if this is considered "tracking" now I'm really confused:

I wouldn't want to be charged for the next version.
By this logic, FitDay PC allows "custom tracking of belly button lint" as well!
