Water Intake Tracker

Each time you drink, tap one of the buttons — a glass, a can, a bottle — or type another amount. The total for today fills toward your daily goal, and the chart shows the last seven days, with a dashed line at your goal and solid bars on the days you reached it. Delete an entry from today's log if you tapped by mistake. Your log starts fresh each day at midnight, in your own time zone.

You can track in millilitres, US fluid ounces or US cups, and switch at any time: every amount is stored in millilitres and converted for display, so changing the unit never changes what you logged. One US fluid ounce is 29.57 ml and one cup is 8 fluid ounces, or 236.6 ml. The starting goal is 2 litres — 2,000 ml, about 67.6 fl oz or 8.5 cups — which is a round number to begin from, not a medical recommendation. How much water a person needs depends on their size, activity, the weather and the food they eat, which also contains water; if you have a health condition that affects fluid intake, follow your doctor's advice instead.

Everything is stored in your browser's own database on this device and never sent anywhere, so the tracker works offline and nobody else can see it. Clearing this site's data in your browser settings, or using a private window, removes the log.
