Connie, as you obviously know, when things go wrong your blood sugars can change very quickly, how often do you think people will sign in, every day, every hour?
And if you had a problem after just signing in, you could then wait another hour before the emergency contact person knows there's a problem and you're in a diabetic coma already. And what if your emergency contact person is away from the phone or in an area with a poor mobile signal?
Sorry, hope you don't think me uncaring, but I just don't see this app really helping anybody at the critical time.
