New in Hydra 3.0: a smarter hydration coach, personal daily checkpoints, clearer warnings, and Premium habit planning. Hydra is the calm, honest water tracker. One tap to log a glass, gentle reminders during your active hours, and real insight into how every drink — coffee, tea, juice, even beer — actually hydrates you, using research-backed hydration coefficients. WHY HYDRA • One-tap quick add — a 250 ml glass in a single touch • 12 beverage types, each with an honest hydration coefficient • Personal daily goal from your weight, activity level, and climate • Gentle reminders during your active hours, never during sleep • Streaks, milestones, and the real health benefits of staying hydrated • Daily status colors, low/high intake warnings, and weekly, monthly, and 90-day insights to see your patterns • Apple Health two-way sync for water and workouts • Siri Shortcuts: "Hey Siri, log 250 ml of water" • Localized in 16 languages, units in ml or fl oz • Editorial design — calm, clear, no hype, no hard-sell PREMIUM, WITHOUT THE GUILT Everything essential is free. Premium adds smart reminders that learn your day, deeper insights, sync between your devices, the Apple Watch widget, and flexible weekly, monthly, or yearly plans — for as little as the price of a single bottled water per month. PRIVACY No accounts. No ads. No tracking. Your hydration data stays on your iPhone unless you turn on iCloud sync. Hydra exists to help you drink enough water — quietly, intentionally, every day.
