Hydra - Hydration Tracker

Hydra is a smart hydration tracker built for athletes and active people. It goes beyond simple water logging — tracking caffeine debt, electrolyte intake, and workout sweat loss to give you a complete Hydration Score.

YOUR HYDRATION SCORE See exactly where you stand with a dynamic score that factors in water intake, caffeine dehydration, and sweat loss from workouts. Your daily goal adjusts automatically based on your activity.

SMART SWEAT TRACKING Log workouts manually or import them from Apple Health. Hydra calculates your estimated sweat loss based on duration, intensity, and activity type — then adjusts your goal so you know exactly how much to replace.

TRACK MORE THAN WATER Log caffeine with automatic hydration debt calculations. Track electrolyte drinks from popular brands like Gatorade, Lucozade Sport, Nuun, and SiS GO. Get the full picture of your hydration, not just water.

INSIGHTS & TRENDS View your hydration history on a colour-coded monthly calendar. Spot patterns with weekly bar charts and detailed daily breakdowns. Track your streak and build better habits.

APPLE HEALTH INTEGRATION Import workouts and heart rate data to automatically calculate sweat offsets. Write your water intake back to Apple Health to keep everything in sync.

SMART REMINDERS Configurable hydration reminders throughout the day. A smart nudge if you're behind on your goal by afternoon. Post-workout reminders to rehydrate.

WORKS OFFLINE All your data is stored locally on your device. No account required. Hydra works fully offline.
