FLOWBIO is transforming how athletes understand and manage hydration. At the heart of our innovation is the world’s most accurate real-time sweat sensor—designed to track your fluid and sodium loss as you train or compete. Paired with our AHi® (Advanced Hydration Intelligence) platform, FLOWBIO delivers personalised insights that guide you to hydrate smarter, perform better, and recover faster.
Hydration is more than just drinking water — it's about understanding what your body really needs. FLOWBIO combines cutting-edge wearable technology with powerful data insights to give you a complete picture of your hydration status, in real time.
What makes it different?
The FLOWBIO Sensor doesn’t just track sweat — it decodes it. By measuring how much fluid and sodium you lose during exercise, the system creates a personalised hydration strategy unique to your body, your session, and your environment.
How does it work?
Our Advanced Hydration Intelligence (AHi®) platform combines live sweat data with training conditions like temperature and intensity. This delivers actionable recommendations before, during, and after exercise — so you know exactly what to drink, when, and why.
Why athletes trust it
From elite endurance athletes to data-driven fitness enthusiasts, FLOWBIO empowers users to avoid dehydration, optimise performance, and recover more effectively — every single day.
Whether you're racing, training, or testing your limits, FLOWBIO gives you the tools to hydrate smarter and perform stronger.
The Sensor captures your sweat and analysis its contents. Proprietary algorithms use the sensor data to estimate your sweat rate and sodium loss. The data is shown on the FLOWBIO App, offering recovery and preparation suggestions and tips to optimise your performance.
Currently, data from the Sensor is accessible only during cycling, running or walking activities. We plan to expand and include other sports as we grow.
The Sensor is designed to be worn on an existing heart rate monitor. We support both optical arm-based monitors and chest straps, offering flexibility in wearing the Sensor either on the upper arm or on your back.
The Sensor measures your sweat rate and sodium loss, helping you optimise your recovery and prepare for training and events by ensuring you replace and bring the necessary fluid and electrolytes.
Our latest data has indicated that we are 90% accurate in lab based conditions. In the field we achieve accuracies up to 83% for our sodium with as little as 23 mg difference (that is 6x less than a pinch of salt). Our fluid loss is 73% accurate with as little as 250mL difference to in-field gold standards.
You can exercise without your phone nearby, but for syncing the Sensor and viewing your data, having your mobile device is essential.
At present, using the FLOWBIO System requires a fitness tracker integrated with the Companion App. We currently support the following integrations:
