Drink enough water, without overthinking it
The Hydration Coach in AI Wellness Pal sets a daily water target that fits you, makes logging a single tap, and shows how consistently you’re hitting it.
A target that fits you
Your daily goal starts at about 35 ml of water per kilogram of body weight (from your profile), adjusted for your profile and activity level, and kept between 1.8 and 4.5 liters. No weight set? It starts at 2.5 liters. You can set your own target any time and switch back to automatic.
Weather-aware hydration (Premium)
Hot or humid day? Set your location and the Hydration Coach adds up to an extra liter to your goal, based on the “feels like” temperature.
One-tap logging
Quick-add 100, 200, 250, 500 or 750 ml, or a full liter, or enter a custom amount. Or just tell your Wellness Pal “log a glass of water”.
Score, streaks and your week
- A hydration score from 0 to 100 that rewards drinking enough, drinking consistently and spreading it through the day.
- Streak milestones like Hydration Hero (7 days) and Hydration Champion (30 days).
- A timeline of today’s drinks and a seven-day view of how often you met your goal.
Reminders, challenges and widgets
Turn on hydration reminders in your notification preferences (they start off), join the 7-Day Hydration Challenge, and add the Hydration Coach widget to see today’s progress on your home screen. With Premium you also get AI insights about your drinking patterns.
