Question 1

What is a hydration tracker and how does Sponge work?

Accepted Answer

A hydration tracker measures how much water you drink during the day. Sponge is a small clip-on hydration tracking device that snaps magnetically onto any water bottle. On-device sensors record each sip automatically and sync to the free Sponge app, so you never have to log water by hand.

Question 2

Does the Sponge hydration tracking device work with any water bottle?

Accepted Answer

Yes. Sponge is designed to clip onto the bottle you already own — insulated steel bottles, plastic tumblers, glass bottles and more. There is no special bottle to buy.

Question 3

How long does the battery last?

Accepted Answer

Sponge lasts about 8 days on a single charge and recharges over USB-C in a couple of hours.

Question 4

Can the hydration tracker lock apps until I drink water?

Accepted Answer

Yes. The Sponge app can lock the apps you choose until you reach your daily hydration goal, turning your phone into a gentle nudge to drink more water.

Question 5

How much does Sponge cost?

Accepted Answer

Sponge is available to pre-order for $59.99 with a 30-day money-back guarantee. The companion app is free on iOS and Android.
