SpongeHow Much Water Should You Actually Drink a Day?
The familiar "eight 8-ounce glasses" guideline is easy to remember and almost entirely made up. Your real water needs depend on your body weight, how active you are, the climate you live in, and even what you eat.
A more useful starting point is roughly half an ounce to one ounce of water per pound of body weight per day, adjusted up for exercise and hot weather. But the only way to know whether you are actually meeting your needs is to measure — which is exactly the gap a hydration tracker like Sponge fills.
Instead of guessing, Sponge records every sip automatically and learns your patterns over time, then sets a personalized daily goal that reflects what your body actually needs rather than a one-size-fits-all number.
