The famous "8 glasses" is a reasonable default, not a law. Australian guidance suggests roughly 2.6 L per day of total fluids for men and 2.1 L for women — and that includes tea, coffee, milk, and the water in food, so the plain-water target is genuinely flexible. Needs rise with heat, exercise, and pregnancy or breastfeeding. The practical approach: pick a goal, hit it consistently for two weeks, and let thirst and energy levels tell you whether to adjust — that's exactly what the streak and 7-day view are for.
The tracker's job is less about hydration science and more about habit mechanics: an in-reach water bottle plus a one-tap log turns "I should drink more water" into a visible chain you won't want to break. Building other habits too? The Habit Tracker uses the same principle across your whole week.
How many glasses of water should I drink a day?
Common guidance works out around 8–10 glasses (250 ml each) of total fluid for adults, with tea, coffee and food moisture all counting. Heat, exercise and body size shift the number — consistency matters more than precision.
Does coffee count towards hydration?
Yes — despite the myth, normal coffee and tea intake contributes net fluid. Count it or don't, but be consistent so your streak means something.
How does the streak work?
Every consecutive day you reach your goal adds one. Today only counts once you've hit the goal, and a missed day resets the chain — that mild sting is the habit-forming feature.
Will my history sync to my phone?
No — history lives in the browser you use it in, on that device. Use it on whichever device is always with you (usually your phone) for the honest count.
Can I change my daily goal later?
Anytime — the goal box updates today and the streak calculation going forward. Start achievable (6–8) and raise it once the habit holds.
