Smart Hydration for Serious Athletes
Hydration is one of those performance levers that often gets overlooked, until it matters. FLOWBIO changes that by giving you real-time, science-backed insights into your sweat, fluid, and sodium loss so you can train and race smarter.
What FLOWBIO Offers
A wearable sweat sensor that measures fluid loss (sweat rate in L/hr), sodium concentration (mg/L), and skin temperature, in real conditions—not just in a lab.
The data feeds into the FLOWBIO app, which uses algorithms to turn raw numbers into personalised hydration strategies: before, during, and after workouts.
Integrations with major platforms and devices (Garmin, Wahoo, Zwift, Coros) so you can use it alongside the tracking tools you already have.
Long battery life (~100 hours), USB-C charging, and flexible mounting options (arm strap or attached to a chest HR strap).
Why It Matters
Prevents common hydration issues like cramps, fatigue, empty legs, and slow recovery by giving you data instead of guesswork.
Lets you fine-tune how much water and electrolytes you need depending on your environment, intensity, and individual physiology: not one-size-fits-all plans.
Can make a difference in performance consistency: staying hydrated means less performance drop-off, better recovery, and fewer surprises on long runs or hot/humid days.
What Makes FLOWBIO Stand Out
High accuracy: in lab settings, up to ~90%; in field conditions still very good for sodium loss (~83%) and sweat rate measurements.
No subscription fees: one-time purchase and you own the tool.
A tool that works for all endurance athletes: runners, triathletes, cyclists. If you care about performance and recovery, this adds meaningful detail to your training plan.
