Why choose hDrop?

Our hydration wearable features proprietary reusable electrode sensing technology, enabling accurate and rapid tracking of sweat metrics.


Our hydration biosensor offers personalized hydration strategies by assessing individual fluid and electrolyte losses during activities.

Why would you pay for every workout?

The burden of sweat patches

While disposable patches for hydration monitoring can seem convenient, they may prove costly in the long run, especially for regular athletes. For those who work out three times a week, the recurring cost of disposable patches, ranging from $5 to $12 each, quickly adds up. This continuous spending, month after month, year after year, can detract from the focus on what truly matters – achieving your peak performance.

Why we do not use disposable patches?

Exercising three times per week adds up a total of 144 workouts per year.
At a $5 per sweat patch the costs add up.

This is what people said about hDrop Gen 1

I am using hDrop to collect hydration information and mix it with all my other wearables. It helps me and my coach plan my races.

Martin L.


Really interesting technology with a lot of potential. I can see how what I drink affects my body and performance.

Jonny C.

Amateur Runner

It is been awesome being able to track hydration on my players. Some of them struggle with heat, and being able to benchmark them helped us buy the appropriate supplements.

Pablo T.

Tennis Coach

This device has the potential to become the next hydration gold standard.  It can detect when I start sweating, how fluid affects my body, and track my skin temperature during my training.
