Nix Solo:
Self Monitoring App

Your sweat is personal. Your hydration should be too.

When it comes to hydration, generic metrics aren’t enough. Performing well and feeling good means understanding and acting on your personal biology — which is why Nix Solo provides you with your unique sweat profile. 

Nix Solo

No more trial and error to identify your optimal hydration strategy. Our revolutionary hydration biosensor, paired with the Nix Solo app, quantifies fluid and electrolyte losses moment-by-moment and sends notifications to your phone, watch, or bike computer to tell you exactly when, what and how much to drink. So you can focus on what really matters - your workout.

Scientific: Evaluates the biomarkers in your sweat, like a portable lab without the needles.

Personalized: Analyzes your sweat moment to moment, not a generic calculation.

Actionable: Quantifies when, what, and how much to drink in real-time during your workout.

Convenient: Integrates with your phone, watch, or bike computer. Lightweight and easy to use.

The System

Rechargeable Pod

Our revolutionary hydration biosensor weighs less than 0.5 ounces and is similar in size to a Garmin watch face. The electronic pod is durable, reusable, and built to last. The pod clips onto a single-use sweat patch and transmits data to the Nix Solo app.

Sweat Patch

The proprietary Nix patch detects electrochemical biomarkers in an athlete's sweat. Once you begin sweating data is transmitted to the Nix Solo app every second. The patch is non-invasive and sticks to the skin with kinesiology tape for flexible adhesion and comfort. The Sweat Patch is single-use only.

Nix Solo

Geared towards the endurance athlete, the Nix Solo app 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.

Available on iOS and Android.

The Science

Nix’s proprietary machine learning algorithms senses the losses from the bicep - both fluids and electrolytes - and extrapolates it to the whole body. Trained and validated on thousands of workouts, with accuracy rates exceeding industry standards.

Convenient Integrations

We've initially launched with Apple watch, Garmin watch, and Garmin Edge integrations. On our radar to launch in the coming months are Strava, TrainingPeaks, Wahoo, and Zwift.
