Medical mobile application Libre Assist

Overview
Libre Assist is a feature within the FreeStyle Libre app that uses generative artificial intelligence to predict potential glucose impact from foods and to provide post‑meal feedback. It delivers near‑instant glucose predictions and personalized food insights based on user‑entered food data (including photos) and continuous glucose monitoring (CGM) readings from supported FreeStyle Libre systems.

Key features

• Snap — Take a photo of your meal; a single photo can be used to log and classify a meal.
• Predict — Libre Assist estimates how the captured food may affect glucose levels.
• Know — Receive feedback after eating to help identify meal‑to‑meal glucose responses.
• Integration — Works with supported FreeStyle Libre CGM systems and displays results in the Libre app.
• Guidance — Provides personalized food insights and helps reveal patterns across meals, activity and insulin dosing.

How it works
Libre Assist analyzes food information provided by the user (including photos) together with CGM data to estimate likely post‑meal glucose impact and to generate follow‑up feedback. Predictions depend on the quality of user input and available CGM readings; actual glucose response may vary with activity, stress, medication, alcohol and other factors.

Availability and compatibility
Libre Assist is available through the Libre app (requires the latest app version). The feature requires a supported FreeStyle Libre system and compatible mobile device/operating system. Examples of supported systems referenced on product pages include FreeStyle Libre 3 and FreeStyle Libre 2 families (including applicable Plus sensors).

Videos and resources
Product pages include demonstration and how‑to videos that show how Libre Assist works and how to add food entries in the Libre app.

Warnings and limitations

• Libre Assist uses generative AI and may not always be accurate; it must not be used to make autonomous treatment decisions.
• Predicted glucose impact is based on user‑provided food details and CGM data; actual impact may differ due to activity, stress, medication, alcohol and other variables.
• Certain app functions may require registration (e.g., LibreView) and are compatible only with specific devices and OS versions.
• Sensor warm‑up period may apply when starting a sensor (60‑minute warm‑up noted).
• Fingerstick blood glucose testing may still be required in specific situations (for example, if alarms and symptoms do not match or during initial sensor hours when indicated).
• Sensor water resistance and wear instructions apply (sensor water‑resistant up to 1 metre; do not immerse longer than specified).

Technical specifications
