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

Your existing watch can now offer health tracking without replacing it.

Hiyd has developed a small, slim disc that attaches to the back of any existing watch to provide health tracking capabilities. The device utilizes microsuction technology, a thin layer of textured silicone with hundreds of tiny pockets, to adhere to the watch face without magnets or adhesives. This method prevents residue and avoids interfering with mechanical watch functions. The sensor, measuring 2.7mm thick and weighing 7 grams, collects biometric data including heart rate, heart rate variability, sleep staging, movement, calories burned, and VO2 max estimations. This data syncs to a companion iOS or Android app. Hiyd's team is training its AI by labeling data from filmed activities to refine sensor accuracy. The app also plans to integrate nutrition tracking, focusing on how dietary habits influence sleep and workout performance, providing personalized insights rather than calorie counting. Hiyd's founder, Salah Batroukh, previously worked as a manufacturing design engineer at Apple.

Hiyd's approach to health tracking by attaching a sensor to existing watches signifies a move toward less intrusive and more integrated wearable technology. The microsuction attachment method, in particular, addresses a key friction point for watch enthusiasts who do not want to compromise their timepiece's aesthetic or function. This innovation could broaden the market for health tracking by appealing to a segment that has historically been underserved by bulky, dedicated devices.

The company's focus on using AI for personalized insights into sleep and nutrition, correlating them with user-specific activity patterns, positions Hiyd as a data-driven wellness platform. This strategy of leveraging existing hardware and offering nuanced feedback, rather than just raw data, could set a new standard for how personal health is monitored and understood. The upcoming Kickstarter launch and existing deposit numbers suggest significant consumer interest in this blend of fashion and advanced health monitoring.
