Nix Biosensors for PC

To train at your peak, you can’t just train hard. You need to train in a way that's informed by your personal biology.

This is especially true when it comes to your unique hydration needs. Yet this information has historically been nearly impossible to access.

At Nix, we built the first biosensor to analyze sweat and provide endurance athletes with personal hydration data – scientifically validated, and delivered in real time.

Once paired with the Nix Hydration Biosensor, you are on your way to understanding your personal biology with the Nix App. We’re the first hydration biosensor of its kind — the only patch, pod, and free app combination to:
- Evaluate the electrochemical biomarkers in your sweat
- Send real-time updates to your phone
- Correlate your sweat data and your training environment with the Nix Index – a composite index of six environmental factors: temperature, humidity, dew point, altitude, wind speed, and solar load.
- Provide post workout Sweat Intelligence via insights on your Sweat Profile including fluid loss, electrolyte loss and sweat composition
- Provide a personal, unique Sweat Profile based on your fluid loss, electrolyte loss and sweat composition

Before your workout, tell the Nix app if you’re running or cycling, and what you’ll be hydrating with. You can also consult the Nix Index to see how your environment - factors like the temperature, humidity, altitude - might impact your hydration needs.

Once you start sweating, our single-use patch begins measuring and analyzing your fluid and electrolyte losses per hour - metrics that represent your unique “sweat composition.” This data is instantly streamed to our app.

The result: you know when, what, and how much to drink in real time, and can prepare for future workouts with more confidence and intention.
