FLOWBIO

Hydration just got personal with the world's most accurate sweat sensor for athletes.

The FLOWBIO Sensor is the world’s first fully reusable sweat sensor that tracks exactly how much sodium and fluid an athlete loses — in real time, every session. It’s like a WHOOP, but for hydration.

And here’s the kicker: most athletes are underhydrating by 2–3x. Even the pros. And it’s costing us all - in performance, recovery, and decision-making.

Session intensity, your fitness, the climate, the season — hydration needs aren’t one-size-fits-all. Until now, no product has personalised it.

The FLOWBIO Sensor & App provides clear, personalised insights that tell you exactly what to drink, when to drink it, and why. It’s your sweat, decoded into simple guidance that helps you stay on top of your hydration, recover better, and perform at your best.
