Your Wrist Knows
When Water's Safe

The smartwatch attachment that tests water quality in seconds

Hippo attaches to your smartwatch and uses your arm's natural motion to spin internal micro-wheels, creating a tiny whirlpool chamber that instantly samples and analyzes water quality. Detect bacteria, heavy metals, and chemical contaminants before you dive in.

✨ The Wow Moment

"You're standing at a murky lake with friends wondering if it's safe to swim. You dip your wrist in, the Hippo indicator pulses blue, and your phone buzzes: 'Unsafe - E. coli detected, enterococcus levels 12x safe limit.' You show your friends and everyone freezes—just like that, you avoided a weekend of serious illness. The moment your wrist saves everyone from getting sick? That's pure magic."
