Glucose at a glance

Trend charts over time and by time of day, with your target range band and simple statistics.

Insulin, meals and medication

Rapid or basal insulin, carbs, medication, physical activity, weight, blood pressure and ketones, on their own or with a reading.

Quick entry

Quick tags, entry from a photo of your meter and import of FreeStyle Libre (LibreView), Excel and CSV files.

Appointments and lab results

A calendar of appointments and routine check-ups, with results such as HbA1c and cholesterol compared over time.

Sharing and family

Share your diary with your doctor or family, manage your child’s diary and get notified when they log a reading.

A diary, not a medical device

Glyco helps you record and organise the data you enter. It does not diagnose, does not suggest treatments and does not calculate doses of insulin or other medication. Treatment decisions always belong to your doctor.
