Frequently Asked Questions

How is my water goal calculated?

The estimate starts at about 35 milliliters of fluid per kilogram of body weight, then adds extra for daily activity, climate and minutes of exercise you logged today.

Does food and coffee count toward the target?

Roughly 20 percent of daily fluid usually comes from food, and most guidelines count caffeinated drinks toward total fluid. Use the number as a general target, not an exact rule.

Can I switch between kilograms and pounds?

Yes — choose your weight unit and the tool converts to kilograms internally, so the result is identical either way.
