Why GlucoFusion
A day full of decisions.
Now with foresight.
Pump and sensor apps show what was recorded. But glucose responds to far more: meals, exercise, sleep, heart rate, and how your body is responding that day.
GlucoFusion brings it all together and learns from your own history, because everyone responds differently. Its on-device AI explains what’s happening under the hood, shows what a workout will likely do before you start, and turns your data into clear, personal summaries.
Forecasts that include your plans
Personalized two-hour forecasts account for insulin, meals and exercise, and show how a planned run would change your glucose.
Private by design
Forecasts are computed on your iPhone, and Apple’s on-device model writes the answers and daily summaries. Your glucose, insulin and therapy data stay on your iPhone and Apple Watch, unless you choose GlucoFusion+, which sends the history you agree to share to GlucoFusion’s servers to train your model.
One connected view
Glucose, trends, insulin on board, and pump status, together in a clear everyday overview.

A forecast
trained on you.
Learning every month.
GlucoFusion+ trains a personalized AI model on your own glucose, insulin, meals and workouts. Your iPhone compares it with your current forecast before it’s ever used, and a new model is built every month.
- Compared on your history first. Your first model is used only if it forecasts your last 14 days better and you tap Use Personalized Model. Each monthly update takes over only when it does better. Switch back anytime.
- You see what’s shared. Glucose, insulin, meals and, if you like, Apple Health data such as workouts and heart rate, encrypted on the way. Your name, photo, birthday, notes and location are never sent.
- Free for everyone. CGM alerts, the two-hour forecast and the lows it shows, pump status and bolus review never require a subscription.
Planned: first month free, then $9.99 a month or $99 a year through the App Store. Cancel anytime.
