Glucose Compass
Type 1 Diabetes Tracker
Track glucose, meals, and insulin with AI-powered insights. Free setup, local data, emergency alerts always free.
Why I Built This
Glucose Compass was built by someone who lives it. I've managed Type 1 Diabetes for 22 years, and I built the tracker I always wanted — shaped by the daily reality of T1D, not a feature checklist.
My goal is simple: help others manage the day-to-day a little more easily, with a tool that respects how much work living with diabetes already takes.
— Alex Bonacci · Type 1 Diabetic of 22 years

Built by Bonacci
Built by a compositor, educator, and developer who believes technology should serve the people who need it most. Glucose Compass was built with the same precision applied to VFX compositing: every pixel matters, every interaction counts, every safety feature is non-negotiable.
