SpongeWe think hydration should be effortless
Sponge started with a simple frustration: every hydration product asked us to do more — log water by hand, buy a new bottle, remember to drink. We wanted the opposite. A tracker that disappears into your day and just works.
Our mission
Chronic mild dehydration is one of the most common and overlooked health issues — and the fixes on the market all rely on willpower. We set out to build a hydration tracker that removes the friction entirely: no logging, no new bottle, no nagging you can tune out.
Built around the bottle you already love
Instead of locking the sensor inside a single bottle, we put it in a tiny clip that works with the bottle you already carry. That one decision makes Sponge flexible enough to fit any routine — at your desk, in the gym bag, or in a parent’s kitchen.
Behavior, not just data
Tracking is only useful if it changes what you do. That’s why the Sponge app pairs gentle, real-time nudges with an optional app-lock that turns your phone into a reason to drink. The result is a habit that actually sticks.
