How to track daily water intake

Guide · ~6 min read

Drinking enough water sounds simple—and is easy to forget. Twilight Water Tracker lets you set a daily goal in milliliters and log every sip with one tap. No install, no account; data stays in your browser and resets at midnight for a fresh day.

How much water per day?

The familiar “2 liters a day” is a reasonable default; needs vary with body size, activity, climate, and health. Twilight defaults to 2000 ml—adjust between about 1500–3000 ml. Progress you can see beats a perfect number you ignore.

How to use Water Tracker

1. Open Water Tracker
2. Tap +200 / +250 / +330 / +500 ml for common glass and bottle sizes
3. Use the custom field for other amounts
4. Undo a mistake or Reset day to clear the log
5. Change your goal in the card below and Save

The ring shows percent complete; hitting the goal shows a small celebration. Today’s entries are listed with timestamps.

Habit tips

• Log +250 ml right after waking up
• Pair water with meals so it becomes automatic
• Pin the tab on phone or desktop—logging takes one second
• Don’t count coffee/tea as water here; use the coffee/tea trackers instead
• Raise the goal by 250–500 ml on workout days
