Sugar Sense is an independent CGM companion platform for people with diabetes and their families. Our servers read your existing CGM around the clock, about every 5 minutes, and push every reading and alert to your devices, so alerts arrive even while the phone sleeps.

Works with: FreeStyle Libre 2/3 (via LibreLinkUp), Dexcom G6/G7 (via Dexcom Share), and any Nightscout site. Manual entries, Apple Health and Health Connect work as logging sources.

Alerts: low, high, urgent low, urgent high, rapid rise, rapid fall, missed readings, and a predictive low that warns about 20 minutes before a forecast low. Urgent alerts can break through Silent and Focus (Apple approved critical alerts). Voice alerts can speak readings aloud.

On every screen you own: iPhone, Android, Apple Watch, web dashboard, Windows system tray, Mac menu bar, browser extensions (Chrome, Edge, Firefox, Safari), and Amazon Alexa. Widgets, Lock Screen Live Activity, Dynamic Island, CarPlay and Siri on iOS.

Care Circle: family and friends follow a loved one for free, with the same live number, graph and alerts. The Family plan shares premium across up to 6 seats.

Management: logbook, Time in Range statistics, AI food scanner (carb ranges, never falsely precise numbers), pattern insights, morning report and CSV export.

Free forever: live monitoring, all glucose alerts, Care Circle following, widgets, the web dashboard, the browser extension, the Windows tray, the Mac menu bar and Alexa. The safety net is never paywalled. Premium adds the Apple Watch app, Live Activity, AI features, Call for Low and more.

Available in six languages: English, German, French, Spanish, Dutch and Georgian. Dose-free by principle: the app never suggests insulin doses. Sugar Sense is a supplemental information tool, not a medical device, and complements your CGM vendor's own app.
