Free for real: log water and 11 other drinks in one tap from widgets, Control Center or Siri. Reminders pause once you hit your goal. No account, no ads, no tracking.
Hydra – Water Tracker is a free iPhone app for tracking your water intake, with drink reminders that pause once you reach your goal. It's the calm, honest water tracker, made by an independent developer.
Log a glass in one tap — in the app, from a widget, from Control Center, from a reminder or with Siri — and see at a glance whether you're on pace for today.
WHY HYDRA
• One-tap logging: +250 ml / +500 ml, or any of 12 drinks
• Home Screen and Lock Screen widgets with buttons to log instantly
• Control Center and Action button control
• Log straight from a reminder without opening the app
• Reminders only during your active hours — and they stop once you reach your goal
• Personal daily goal from weight, activity and climate, or set your own
• Pace-aware status: Hydra compares your intake with the time of day
• Edit or delete any entry
• Apple Health: every drink is saved as water
• Siri in 24 languages: "Log water in Hydra", "How much have I drunk in Hydra"
• Transparent science: hydration factors based on the Beverage Hydration Index, with sources in the app
• ml or oz; text scales with your iPhone's text size
