hDrop App

Turn every workout into a personalized sweat test.

The hDrop app connects to your reusable hDrop sweat sensor to track sweat rate, total fluid loss, sweat sodium concentration, sodium loss, potassium loss and near-skin temperature during exercise.

Built for runners, cyclists, triathletes, endurance athletes, coaches and teams, hDrop helps you understand how heat, intensity, duration and training conditions affect your sweat and electrolyte losses. Use real-time data and detailed workout summaries to build a hydration strategy around your own body.

PERSONALIZED SWEAT AND HYDRATION INSIGHTS

• Monitor sweat rate in real time
• Track total fluid loss during exercise
• Measure sweat sodium concentration
• Estimate total sodium and potassium losses
• Review workout summaries and compare sessions
• Export activity data for deeper analysis
• Refine your fluid and electrolyte strategy over time

TRAIN WITH DATA FROM YOUR BODY

Sweat rate and electrolyte losses are different for every athlete and can change from one workout to another. hDrop helps you identify your personal sweat profile so you can make better-informed decisions about fluid and sodium intake during running, cycling, triathlon, hiking, indoor training, heat training and other endurance activities.

REUSABLE AND BUILT FOR REAL TRAINING

Unlike single-use sweat patches, the hDrop sensor is reusable and designed for repeated testing during real workouts. Track your sweat response indoors, outdoors, in the lab or during competition, then use your results to improve your hydration planning over time.

FOR ATHLETES, COACHES AND TEAMS

Use hDrop for individual training, athlete testing, team sessions and performance monitoring. Review sweat data after each activity and use objective measurements to support more personalized hydration and electrolyte strategies.

HDROP SENSOR REQUIRED

The hDrop Android app requires a compatible hDrop wearable sweat sensor. Available features may depend on your sensor, firmware and connected device.
