hDrop Debuts in Europe via RCD Espanyol Partnership

Europe, We’re Live, RCD Espanyol Uses hDrop’s Reusable Sweat & Hydration Sensor as We Launch Across Europe

We’re excited to announce hDrop’s official entry into the European market through a new distribution partnership with From Minus Zero, opening access for pro teams, dedicated amateurs, and retail consumers throughout the region.

Why Sweat Data Matters (And Why Now)

Hydration isn’t guesswork: performance and recovery hinge on replacing the right amount of fluid and electrolytes. hDrop’s wearable sweat biosensor gives athletes real-time visibility into individual sweat rate plus sodium and potassium losses, then turns those numbers into practical, personalized hydration strategies to boost in-competition output and speed recovery.

Early Adopter Spotlight: RCD Espanyol

LaLiga club RCD Espanyol is the first European team to integrate hDrop into daily training. Their sports science staff monitors each player’s sweat profile and tailors electrolyte replacement protocols accordingly, an approach aimed at reducing dehydration-related performance drops and improving late-match resilience.
Huge thanks to Espanyol’s medical and nutrition teams for the collaboration so far.

hDrop Provides Accuracy You Can Trust

Preliminary, independently validated data show our sensor delivering 92% accuracy for sweat-loss measurement and 87% accuracy for sweat sodium loss, the highest precision we’ve seen reported for a wearable sweat sensor. Ongoing independent validation studies at leading sports-science institutes are underway, with peer-reviewed results expected later this year.

Built for Athletes

Unlike single-use sweat patches, hDrop is fully reusable, pairing a skin-safe sensor with our companion mobile app. This reduces waste while delivering a continuous learning loop for each athlete. Inside the experience you get:

Pre-competition planning: individualized hydration & electrolyte guidelines drawn from historical sweat profiles.
In-session monitoring: live feedback on fluid and sodium losses to help prevent performance-limiting dehydration.
Post-session analysis: deep reports to refine training and recovery strategies over time.

Multi-Sport Momentum
