About Hydra: Water Tracker
Hydra is a hydration tracker built around a single gesture: drag up anywhere on the home screen and watch the water rise to where you logged. Most water apps use a generic 2L target. Hydra calculates yours from your weight, sex, activity level, and climate — then bumps it up automatically when you take creatine. Because creatine pulls water into your muscle cells, you actually need more. DESIGNED AROUND THE WAY YOU DRINK • Drag to pour — pan up anywhere on the home screen • Quick-add presets for a glass (250ml), bottle (500ml), or shaker (700ml) • Custom amounts for anything in between • A live water-level background that fills as you progress CREATINE-AWARE TARGETS • One-tap daily creatine pill • Target adjusts automatically: +500ml per 5g dose • Personalized baseline from weight, sex, activity, and climate STREAKS THAT FORGIVE A BAD DAY • Daily streak counter • Personal best tracking • One streak freeze per week • Milestone glow effects every 7 days PRIVATE BY DEFAULT • No account, no login, no email • No analytics, no trackers, no ads • Everything stays on your device Drag to pour. Hit your goal. Build the streak. --- SUBSCRIPTION DETAILS Hydra Pro is available as an auto-renewing subscription: • Hydra Pro Monthly — £4.99 / month • Hydra Pro Annual — £29.99 / year (save 50%) Prices may vary by region.
