Hydrium

Try every Plus feature free for 14 days: smart reminders, full history, Apple Watch and automatic iCloud backup.

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 • 7-day, 30-day, 12-month and all-time history • Charts and a breakdown by beverage • 12 badges to unlock, day streaks

APPLE WATCH AND HEALTH • Full companion app for Apple Watch, synced with your iPhone in real time • Watch face complication: progress ring and volume in ml (circular, corner, rectangular and inline) • Your drinks are written to the Health app automatically • Reads your weight and workouts to refine your goal

AUTOMATIC ICLOUD BACKUP • Optional, turned on in Settings › Data: a daily copy of your data in your iCloud Drive (Hydrium folder in the Files app), the 7 latest are kept • Restore from iCloud in a few taps, after a reinstall or on a new iPhone • Your data stays in your own iCloud account: Hydrium has no server • Manual backup and restore (JSON file) are still available

14-DAY FREE TRIAL • Try every Hydrium Plus feature free for 14 days, no subscription • When the trial ends, the app returns to the free version: your data is kept, and the containers, beverages and styles created during the trial stay hidden until you buy Hydrium Plus
