Not sure how much water you should drink a day? Glug calculates your ideal daily intake based on your weight, height, age, and activity level, then helps you track every sip. A hydration tracker that actually knows you.
💧 PERSONALIZED HYDRATION GOALS
Glug calculates how much water you should drink based on your body metrics and lifestyle. See exactly how your goal is built: base intake, activity level, life stage, climate, and exercise, all visible in a clear goal breakdown. Pregnant or breastfeeding? Toggle life-stage adjustments that add the recommended extra intake. In a hot climate? Glug accounts for that too.
🏃 SMART WORKOUT ADJUSTMENTS
Your water needs change when you exercise. Glug connects with Google Health Connect to read your workouts and automatically add extra hydration to your daily goal based on type, duration, and intensity. Your target updates in real time as you move. Every drink you log is also written back to Health Connect, so your hydration data appears alongside all your other health metrics.
⏰ TIMED INTAKE SCHEDULING
Drink the right amount at the right times. Choose from preset schedules: Early Bird for steady hydration across the day, or Intermittent Fasting mode optimized for 16:8 windows. Smart reminders respect your schedule and won't nag if you're already on track.
☕ FULL BEVERAGE LIBRARY
Go beyond water. Log espresso, cola, energy drinks, or create custom beverages with precise volume, caffeine, sugar, and optional sodium and potassium tracking. Region-specific presets included, from Lemon Water to Agua de Avena to Apfelschorle. Your most-used drinks appear first for faster logging.
📊 STATS, STREAKS & INSIGHTS
Track your consistency with current and best streaks, weekly bar charts, and a 28-day heatmap. View daily, weekly, and monthly averages, calculated from active days only. Separate stats tabs for caffeine, sugar, and electrolytes. Plus a fresh hydration tip on your dashboard every day.
📲 HOME SCREEN WIDGET & WEAR OS
Log water from your home screen with a single tap. See your daily progress (consumed, remaining, and goal) without opening the app. Wear OS companion lets you track and log straight from your wrist.
☁️ CLOUD BACKUP & SYNC
