HydroFlow — Hydration Assistant

Stay hydrated. A privacy-first, adaptive hydration companion — no account, no tracking, everything stays on your computer.

HydroFlow — Stay hydrated. Stay productive. HydroFlow is an intelligent hydration companion that helps you build a lasting water-drinking habit while you work — without turning into another repetitive alarm you learn to ignore. Instead of pinging you every hour no matter what, HydroFlow pays attention to how your day is actually going: how long since your last drink, how close you are to today's goal, whether you're active or away from your keyboard, and whether you tend to skip reminders at certain times. It uses all of that to decide when a reminder will actually help — and it backs off automatically if you keep snoozing or skipping. WHY HYDROFLOW IS DIFFERENT • Adaptive reminders, not a fixed timer — the interval shortens when you're behind pace and eases off when you're ahead, or when you've been dismissing reminders • Respects your schedule — working hours, lunch break, sleep hours, weekends, and a one-tap vacation mode all pause reminders automatically • Six reminder styles — from a standard notification to a gentle nudge, a silent toolbar badge, or a friendly floating card — each with Drink Now / Snooze / Skip actions TRACK YOUR WAY • Quick-add buttons for your everyday cups and bottles, plus fully custom container sizes • Milliliters, liters, fluid ounces, or cups — switch anytime • An animated water bottle and progress ring that fill up as you go SEE YOUR PROGRESS • Dashboard with today's intake, streaks, and a weekly trend chart • Statistics page with lifetime totals, best/toughest days, daily and monthly trends, and an 18-week hydration calendar heatmap • A Wellness Score that blends today's progress, consistency, and reminder responsiveness into one number • Local Insights that notice real patterns in your own habits — like which days you're most consistent, or when reminders actually work for you — and say nothing when there isn't enough data to back it up STAY MOTIVATED • Achievements, XP, and levels that celebrate real milestones — first glass, streaks, lifetime totals — with a little confetti along the way • A full history timeline of every drink, reminder, and milestone BUILT AROUND YOUR PRIVACY No account. No login. No analytics, telemetry, or tracking of any kind. HydroFlow never reads your browsing history, passwords, typed text, or clipboard. Every bit of your hydration data stays in this browser's local storage — nothing is ever uploaded anywhere. Export a full backup or permanently delete everything, anytime, from Settings. Beautiful in both light and dark mode, with accessibility options for reduced motion, high contrast, and larger text. Stay hydrated. Stay productive.
