Where has this app been all my life????
 

By chance, I only discovered GB yesterday, although I had invented it (or something like it, but not as good as it!) in my mind many times over since I developed type 1 diabetes 40+ years ago. I think it is absolutely brilliant and I really want to extend my thanks and appreciation to all those involved in this life enhancing project:)

Welcome to the Forum! :) Enjoy the app! :D
