Revolutionary sweat science

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.
