Hydrium

Hydrium helps you drink enough water every day, without having to think about it.

During setup, Hydrium calculates your daily goal from your weight, activity level and climate, with adjustments for pregnancy, breastfeeding, workouts and hot weather.

SIMPLE TRACKING
• Log a drink in one tap: glass, mug, flask, bottle or a free amount
• 4 animated visuals to watch your progress: bottle, silhouette, plant, ring
• Drink type (water, tea, coffee, juice, soda...) is factored into your real hydration

SMART REMINDERS
• Reminders at a regular interval or at fixed times
• Adaptive reminders: Hydrium automatically spaces out the reminders left in your day based on the time and how much you still need to drink
• Automatic snooze after a large drink, reminders pause once you reach your goal

HISTORY AND MOTIVATION
