Daily Water Habit Tracker

Smart water goals based on your body + live weather. Apple Health sync, streaks, science-backed tracking. Free. No ads. No subscription.

Build the daily water habit that changes your life.

Daily Water Habit Tracker uses peer-reviewed science to calculate your personal hydration goal - then helps you hit it every day with smart reminders, live weather awareness, and the most honest hydration tracking on the App Store.

YOUR PERSONALISED GOAL Not the generic "8 glasses a day" advice. Your goal is calculated from your body weight, gender, activity level, and local climate - based on National Academies of Sciences, WHO, and EFSA research. Males need 35 ml/kg/day, females 31 ml/kg/day. Updating your weight in Apple Health automatically updates your goal.

LIVE WEATHER AWARENESS Connects to Apple WeatherKit to detect your real local temperature and humidity every day. Hot afternoon in a tropical city? Your goal adjusts automatically. The only free water tracker that responds to your actual environment.

APPLE HEALTH SYNC Every drink you log is written to Apple Health instantly. Body weight syncs automatically from Health so your goal is always accurate. Works with Apple Watch.

LOG ANY DRINK Track water, coffee, tea, juice, milk, soda, coconut water, and sports drinks - each with its research-accurate hydration percentage (Maughan et al., 2016 Beverage Hydration Index). Coffee counts as 95%, not 80%. Soda counts as 90%, not 70%.

Create your own custom drink types with a name, icon, colour, and hydration percentage. "Protein Shake", "Herbal Tonic", "Energy Drink" - whatever you drink, you can track it.

SMART REMINDERS THAT KNOW WHEN TO STOP Reminders respect your wake and sleep times, always in your local timezone. Already logged water recently? The next reminder is automatically skipped. Hit your daily goal? All remaining reminders stop immediately - no more being nudged after you've already succeeded. They reset fresh every morning.

Special reminders: morning motivation at wake time, evening catch-up at 8pm if behind, and a celebration the moment you hit your goal.

ROUTINE REMINDERS Create named water reminders built around your personal schedule. Morning, meals, gym, bedtime - any routine, any time, any days of the week. Each gets its own emoji, name, amount, and repeat schedule. Perfect for building consistent habits.

STREAK & MILESTONES Build your daily streak. A built-in grace day protects it if life gets busy. Milestone celebrations at 3, 7, 14, 21, 30, 50, and 100 days. Track your all-time best streak alongside your current one.

INSIGHTS 7-day bar chart, weekly average, drink type breakdown, goal achievement rate, and total days logged. See your habits forming over time.
