Hello from Denmark - and 500 Rule ??

Hi There !!

I am a Diabetic Type 1 from Denmark.
I have had a history with a lot of problems (lost sight on one eye and bad kidneys) propaply due to bloddsugar levels going up and down a lot

I have Just published an App int the AppStore called DiabetesDocs
My App supports taking unlimited test and supplies me with a good overview for the latest days of bloodsugar, meals,medicine and motion
and i helps me decide how much insulin i need - depending on current bloodsugar level and carbs in my meal.

My app has had a great effect on myself and my goal is to make it a "cant live without" for diabetics

So I was just wondering - are you english people familiar with the 500 Rule and 100 Rule when calculation your medicine or
do you use something different ???

Ok thanks !! I Actually do the same in my app I just specify the Ratio
which shoul be calculated like this (all insulin per day/500)
because when i calc it with the 500 Rule i dont exactly hit the Ratio I currently use
