FAQ

Does coffee count? +
Yes, partially. Caffeinated drinks are still net positive for hydration — just less than water. Alcohol is the only common drink that's actually dehydrating.
Food has water too? +
~20% of your daily water comes from food (fruits, vegetables, soups). So you don't have to drink the full number in liquid.
