Hiyd’s slim sensor turns standard watches into health trackers

The device uses microsuction technology—a textured silicone surface with hundreds of tiny air pockets—to grip the back of a watch case without the need for magnets or adhesives. Measuring 2.7 mm in thickness and weighing 7 grams, the sensor tracks heart rate, sleep quality, movement, and VO2 max. The startup is currently training its AI models by labeling video datasets of various physical activities to ensure accurate heuristic analysis within its companion iOS and Android app.

Beyond basic biometrics, the company plans to integrate personalized nutrition and lifestyle insights. Instead of simple calorie counting, the software intends to correlate user habits with physiological outcomes, such as how late-night workouts or specific dietary choices impact sleep cycles. Batroukh, who spent seven years at Apple, leads the venture alongside CTO Omar Shakir and head of software Mahamad Charawi. Following a debut at TechCrunch Disrupt’s Startup Battlefield, Hiyd will launch a Kickstarter campaign in November, having already secured over 16,000 pre-order deposits.
