hDrop™ Sweat Zones

A new feature that allows you to understand your hydration in an easy and intuitive way during exercise. It is a tool to help you stay aware of your status, complement your hydration strategy, and be more prepared. It does not, in any case, replace the advice of a professional.

Concentrated Zone

This zone indicates that your sweat has less water and more salt. It could mean you might not be drinking enough plain water. 

Target Zone

This is the zone where the concentration of salts and the volume of your sweat are balanced, indicating that your sweat levels are within your regular range. 

Diluted Zone

This zone shows that your sweat has more water than usual. It suggest you might be drinking too much plain water, diluting the salts in your body and potentially needing more electrolytes. 

Operational Modes for our Sweat Sensor

Thumb Test

Place your thumb on the sensor for 80 seconds and receive an immediate range hydration score, offering an estimated snapshot of your current hydration status. (Good, Medium, Low)

Light Activity

Designed for individuals engaged in less strenuous activities like working at a desk, resting, or taking a light walk. Simply place your hDrop on your upper arm, wait to allow sweat capture, and then receive notifications.
