Sugar Sense
Sugar Sense streams live glucose from your FreeStyle Libre, Dexcom, or Nightscout account into one dashboard on iPhone, Apple Watch, Android, and Wear OS. This healthcare app adds predictive heading-low alerts, customizable thresholds, and a Care Circle so family members receive the same urgent notifications.
Abbott and Dexcom ship their own apps, but Sugar Sense layers extra alert types and cross-platform widgets on top of your existing sensor account. The predictive low warning estimates when you may hit a low in about 15 minutes, and the free tier keeps live glucose, every core alert, and family sharing at $0 forever.
People with type 1 or type 2 diabetes, parents tracking a child's CGM, and caregivers use Sugar Sense to glance at glucose from the Lock Screen, Dynamic Island, or watch face. Premium at $9.99 per month adds AI food-photo carb estimates, Apple Watch complications, and PDF reports for clinic visits.
