The first biosensor to analyze sweat and provide endurance athletes with personalized hydration data — scientifically validated and delivered in real time.
Nix Hydration Biosensor

Our lightweight biosensor continuously measures sweat throughout your workout and sends personalized notifications to your phone or watch in real-time to tell you when, what, and how much to drink, ensuring that you stay properly hydrated.

Measure what matters

Even mild dehydration can initiate physiological changes that impose cardio-respiratory stress, compromise thermoregulation, impose fatigue, and significantly impair physical and cognitive performance - often times before you even feel the symptoms.
