About Hydra: Water Tracker & Intake
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 FREE, FOR REAL Logging, all drinks, reminders, widgets, 7-day history and Apple Health are free. PREMIUM • Smart reminders that count from your last drink • 30- and 90-day history with insights (peak time, drink mix, alcohol) • Linen and Slate themes PRIVACY No account. No ads. No tracking.
