FLOWBIO combines advanced sweat sensor technology with personalised hydration insights to help athletes perform better, recover faster, and stay on top of fluid and sodium loss.

Discover more about FLOWBIO

FLOWBIO exists to help endurance athletes better understand how hydration impacts performance. By analysing sweat and sodium loss during exercise, the brand gives athletes access to data that was previously difficult to measure outside of laboratory environments.

Using advanced biosensing technology and proprietary algorithms, FLOWBIO delivers personalised hydration insights tailored to the individual athlete. The result is a smarter, more precise approach to fuelling, recovery and heat management.

The brand has quickly become recognised for its science-led approach to hydration. Independent validation studies conducted in partnership with leading sport science researchers demonstrated strong agreement between FLOWBIO and established laboratory reference methods for measuring sweat loss and sodium concentration.

From runners and cyclists to triathletes and endurance enthusiasts, FLOWBIO is helping athletes move beyond generic hydration advice and make performance decisions based on their own physiology.

FAQs

HOW DOES THE SENSOR WORK?

The FLOWBIO Sensor captures your sweat and analyses its contents. Proprietary algorithms use the sensor data to estimate your sweat rate and sodium loss. Results are shown in the FLOWBIO App, with recovery and preparation guidance to help you optimise performance.

WHAT ACTIVITIES CAN I USE THE FLOWBIO SYSTEM FOR?

The FLOWBIO System currently supports cycling, running, and walking. Further sports will be added as the platform develops. Contact FLOWBIO at team@flowbio.com for enquiries about additional modalities.

WHERE IS THE SENSOR WORN?

The FLOWBIO Sensor is designed to attach to an existing heart rate monitor. It supports both optical arm-based monitors and chest straps, giving athletes the flexibility to wear it on the upper arm or across the back.

HOW ACCURATE IS THE SENSOR?

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 180mg 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.

We also independently validate our sensor, which showed that we are no different to the in-field gold standard for sodium (L’AquaTwin) and not significantly different to the gold standard for fluid loss. We tested this in hot and dry and hot and humid conditions for indoor cycling. You can find the validation study at frontiersin.org.
