What is Water Drink Reminder & Hydration Tracker?
Water Drink Reminder & Hydration Tracker helps you stay hydrated with configurable drink reminders and a visual daily intake log. Set your goal in glasses or milliliters, tap quick-add buttons as you drink, and start a gentle interval timer while this tab is open. Everything is stored locally on your device — no accounts, no uploads, no tracking.
Hydration logs and reminder settings are stored only in your browser's localStorage. No data is uploaded or shared.

Tips & common mistakes
- Keep this tab open or pinned for the most reliable reminders — background tabs may be throttled by your browser.
- Use quiet hours so you are not nudged late at night or early morning.
- Log water right after drinking so your daily total stays accurate.
- Aim for steady sips across the day rather than chugging at the end.
- On iOS Safari, system notifications are limited — rely on the in-tab sound and visual alert.
Who uses this tool?
- Office workers who forget to drink water during long focus sessions.
- Students and remote workers building a simple hydration habit.
- Anyone tracking daily water intake without signing up for another app.
- People recovering from illness who need gentle, regular hydration prompts.
Frequently asked questions
- Do reminders work when the browser tab is closed?
- Not reliably. Reminders are designed to work while this page is open. Browsers throttle background tabs, and iOS Safari does not support dependable closed-tab notifications. For best results, keep the tab open or pinned.
- Is my hydration data uploaded anywhere?
- No. Your goal, intake log, settings, and reminder state are saved only in your browser's localStorage on this device. Nothing is sent to our servers.
- How does the daily reset work?
- Each calendar day starts fresh at midnight in your local timezone. Yesterday's total moves into the 7-day history chart; today's counter resets to zero.
- What are quiet hours?
- Quiet hours let you set a time range (for example 10 PM to 7 AM) when reminders will not fire. You can still log water manually during quiet hours.
- How much is one glass?
- One glass is 250 ml by default. You can also log exact amounts with the +250 ml and +500 ml buttons, or switch your goal display between glasses and milliliters.
- Why did I not get a notification?
- Check that you clicked Enable notifications and allowed permission in your browser. Notifications require the tab to be open for reliable delivery on most platforms. The in-tab sound and visual overlay still work when sound is enabled.
