Your Hydration Just Got Personal - Meet the FLOWBIO Sensor

Hydration has always been a cornerstone of athletic performance, but until now, it’s been a calculated guess rather than personalised, data-driven insights. With a 2% drop in body mass from dehydration impacting performance, personalised hydration is a serious edge. But FLOWBIO - Sensor, the world’s most accurate sweat sensor that brings lab-quality sweat analysis to your daily training. The FLOWBIO helps any endurance athlete take the guesswork out of hydration and turn it into a personal advantage.

What is the FLOWBIO Sensor?

The FLOWBIO is a wearable hydration sensor designed to measure sweat rate and sodium loss in real time. It sits on an existing heart rate monitor strap and collects data during exercise.

This data syncs with the FLOWBIO app.
The app cost is built into the one-off purchase price.
It’s the first sweat-testing system of its kind designed for continuous use in real-world conditions, not just in a lab. This means that you can collect your personal sweat and sodium losses in any given environment at any given fitness and life stage.

The Science

Since we lose electrolytes through sweat, it's important to replenish our body's stores with a hydration mix that closely aligns with our sweat composition. However every hydration mix comes with its own variation of electrolytes. If we choose a mix that has too little sodium you risk the chance of cramping, becoming fatigue, or worse hyponatremia. Too much, may lead to dehydration and stomach cramps.

FLOWBIO has the ability to track both water and sodium loss with high accuracy [up to 90% in lab settings and 83% in the field].
The system adjusts hydration recommendations based on individual needs and environmental factors like heat or humidity.
FLOWBIO connects with Garmin, Zwift, COROS, and Wahoo.
The companion app interprets raw data into clear, actionable advice tailored to your current training conditions and recovery goals. FLOWBIO ensures your hydration strategy evolves with your body and the demands of the environment.

Whether you're training for your next marathon, pushing personal records on the bike, or simply want to feel stronger and smarter in your workouts, FLOWBIO is the hydration upgrade your body deserves.
