Water Day Tracker

Stay hydrated, feel better. Every day.
WaterDay tracks your daily water intake and reminds you to drink throughout the day — based on your personal profile, not a generic goal.
Your personalized hydration goal
WaterDay calculates your ideal daily water intake using your weight, age, gender, activity level, and climate. Your goal updates automatically as your lifestyle changes.
Track every sip
Log water, tea, coffee, or other drinks in seconds. See your daily progress at a glance with a clean, intuitive dashboard.
Smart reminders that fit your schedule
Set your wake-up and bedtime, choose a reminder interval (every 30 minutes to 3 hours), and WaterDay handles the rest. Notifications arrive only during the hours you're awake.
Home Screen Widget
Add the WaterDay widget to your home screen to log drinks and check your progress without opening the app.
