Flowbio FAQ
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.
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. If you are interested in learning more about the accuracy of the system behind the Sensor, you can request our whitepaper here.
You can exercise without your phone nearby, but for syncing the Sensor and viewing your data, having your mobile device is essential.
