Built by an athlete with Type 1.

I've had Type 1 for thirty years. I run marathons and race triathlon for GB in my age group. I built Glucose Insights because I wanted to see my glucose against my training instead of guessing, and nothing did that. Every session I log makes the next one easier to plan.
