ADVANCED HYDRATION INTELLIGENCE
THE PROBLEM.
Most athletes don’t know how much fluid or sodium they lose when they sweat - and that guesswork leads to cramping, disrupted post-race sleep, empty legs, and dehydration hangovers across training, racing, and recovery. Hydration is deeply personal. Yet most hydration plans aren’t.
THE SOLUTION.
FLOWBIO uses the world’s most accurate sweat sensor to measure your fluid and sodium loss in real time, with that data powered by AHi® - Advanced Hydration Intelligence - the technology that combines your sweat profile, effort, and environment to deliver personalised hydration insights, so you know exactly what to drink, when, and why.
HOW IT WORKS.
The FLOWBIO Sensor measures how much fluid and sodium you lose when you sweat in real-time, with the App acting as your hub - displaying key metrics like fluid loss, sodium loss, and sodium concentration, while using your sweat data, session intensity, and environmental conditions to deliver personalised hydration recommendations through the integrated Hydration Planner.
PRE SESSION
Know the exact volume of water and concentration of sodium amount to consume in the build-up to your session or race.
DURING SESSION
Your personal sweat profile evolves and adapts to your fitness level, workout intensity and environmental conditions.
POST SESSION
Understand how to replenish your body with the right volume of water and amount of sodium to enhance recovery post activity.
FILL THE GAP
The Neglected performance pillar
Hydration is a neglected pillar of an endurance athlete’s regime. A clear understanding of your daily fluctuating Sweat Profile is foundational to becoming a stronger, faster athlete.
UNLOCK YOUR NEXT-LEVEL
ADVANCED HYDRATION INTELLIGENCe.
Think of AHi® as the brains behind your FLOWBIO System - the sensor & app working together. It takes the data from your sweat - fluid & sodium loss (salt) - mixes it with key information like temperature and intensity, and turns it into personalised advanced hydration insights. Your sweat, decoded - so you know exactly what to drink, when, and why.
"Hydration is such a key parameter for pushing performance. If we can learn how our body is functioning as an individual in real time.... it's gamechanging."
Tim Don
Ironman World Record Holder
"As a practitioner, I couldn't be more excited to get all my athletes using this to nail their hydration strategy."
Alan Murchison
The Performance Chef
“Working with FLOWBIO at the National Running Show was a great way to engage runners and bring hydration into the conversation. The AHi® Lab sessions gave them a better understanding of their sodium needs, creating a natural connection to our electrolyte range and how it can support their performance.”

THE SCIENCE OF SWEAT.
Sweating is essential for regulating body heat. You lose water and electrolytes in the process. These losses will change depending on the environmental conditions, exercise intensity, and fitness levels.
By understanding and managing your own water and electrolyte needs, you can mitigate against the negative effects dehydration has on your performance, including decreased endurance, impaired decision-making, reduced coordination, muscle cramps, fatigue and even heat stroke.
Frequently Asked Questions
HOW DOES THE SENSOR WORK?
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.
WHAT DOES THE SENSOR MEASURE?
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.
HOW LONG DOES THE BATTERY LAST?
The battery life is 100+ hours and the device can be charged using a USB-C cable.
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. If you are interested in learning more about the accuracy of the system behind the Sensor, you can request our whitepaper here.
DOES THE SENSOR USE A NEEDLE LIKE THE SUPERSAPIENS?
No, the Sensor does not have a needle. We collect sweat through a tiny channel using the pressure exerted by your sweat glands.
