What is Sugar Sense?
Sugar Sense is a comprehensive, AI-enhanced diabetes management application designed to provide real-time glucose monitoring, predictive alerts, and family sharing. It serves as a centralized hub for individuals living with diabetes, integrating seamlessly with popular Continuous Glucose Monitors (CGMs) like FreeStyle Libre and Dexcom, as well as the open-source Nightscout platform. The app transforms raw glucose data into actionable insights, offering features like Time in Range statistics, an AI-powered food scanner for carb estimation, and customizable alerts. It functions as a critical safety net and daily management tool, built by someone with over 12 years of personal experience with type 1 diabetes.

Frequently Asked Questions
Which CGMs does Sugar Sense work with?
It works with FreeStyle Libre (via LibreLinkUp), Dexcom G6/G7/ONE (via Dexcom Share), and any self-hosted Nightscout site. It can also read manual entries or glucose data from other apps via Apple Health or Health Connect.
Does Sugar Sense work without a CGM?
Yes. You can manually enter blood glucose meter readings, and the app will still provide graphs, statistics, and a logbook. However, real-time automatic alerts require a live CGM connection.
Is my health data private and secure?
Absolutely. Sugar Sense states it is GDPR compliant, encrypts data in transit, and ### never sells or trades user data. You maintain ownership and can export or delete your data at any time.
Can my family see my glucose data?
Yes, through the "Care Circle" feature. You can invite specific people who will then receive shared alerts and can view your real-time glucose trends, all with your explicit permission.
Does Sugar Sense replace my official CGM app or medical device?
No. It is a companion application for data visualization, alerting, and insights. It is not a medical device and should not be used as the sole basis for treatment decisions. Always consult your healthcare provider and follow the guidance from your medical-grade CGM system.
What platforms is it available on?
Sugar Sense is available as a native app for iPhone, Apple Watch, Android phones, and Wear OS watches, keeping all data in sync across your devices.
Is there an Alexa skill?
Yes, a free Alexa skill allows you to ask, "Alexa, ask Sugar Sense what's my glucose?" to get your latest reading and trend on compatible Echo devices.
