Apple’s long-rumored blood sugar tracking for Apple Watch remains out of reach, despite years of research, patents, and rising consumer expectations. The U.S. Food and Drug Administration has not cleared any smartwatch or smart ring to measure or estimate blood glucose without piercing the skin, warning that inaccurate readings could drive dangerous dosing or treatment decisions for people with diabetes.
