Hiyd is a health tracker that attaches to the watch you already wear

A new startup founded by former Apple engineers, Hiyd, has introduced a novel health tracking device designed to integrate seamlessly with existing timepieces. Unlike traditional wearables that require users to replace their current watch or use bulky accessories, the Hiyd sensor attaches directly to a watch without the need for magnets or adhesives. This innovation aims to provide advanced biometric monitoring—such as heart rate and activity tracking—while allowing users to maintain their personal style and preference for traditional or luxury watches. By focusing on non-invasive attachment technology, the company seeks to bridge the gap between high-end horology and modern health data collection. The device represents a shift in wearable tech, prioritizing convenience and aesthetic continuity over the need for dedicated smartwatches. As the health tech market continues to expand, Hiyd's approach offers a unique solution for consumers who want health insights without sacrificing their favorite wristwear.
