Description
hDrop is the first wearable sweat sensor designed to extract data from your sweat during exercise.
Independently validated research shows that hDrop is the world’s most accurate wearable sweat sensor, helping athletes understand how much fluid and sodium they lose while training.
Whether you are preparing for a marathon, triathlon, cycling event, or intense training session, hydration strategy matters. Generic hydration advice does not account for the fact that every athlete sweats differently. hDrop helps you personalize your hydration based on real physiological data.
Measure What You Lose in Sweat
hDrop continuously monitors your sweat during exercise and provides insights that help you understand your body's hydration demands.
Track key metrics including:
• Sweat Loss – Estimate how much fluid you lose during training
• Sweat Sodium Loss – Understand electrolyte loss to guide sodium intake
• Sweat Rate Trends – Learn how your hydration needs change with intensity and environment
Build Your Personal Hydration Strategy
Use your sweat data to create a hydration plan tailored to your physiology.
With the hDrop app you can:
• Analyze sweat loss across workouts
• Understand sodium losses during exercise
• Compare sessions in different weather conditions
• Improve hydration planning for races and long training sessions
Designed for Endurance Athletes
hDrop is built for athletes who depend on hydration precision:
• Triathlon
• Marathon and running
• Cycling
• Trail and ultra endurance sports
• Heat training and high-intensity workouts
Scientifically Validated Technology
hDrop technology has been independently validated by university research, demonstrating high accuracy in estimating sweat loss and sodium loss during exercise. The system was developed with a focus on translating laboratory sweat testing into a wearable field solution for athletes.
Unlock Advanced Features with hDrop Lab
The optional hDrop Lab membership provides deeper analysis tools, advanced hydration insights, and personalized hydration guidance based on your sweat profile.
Hydrate smarter. Perform better.
