THE MISSING LAYER

You track what your body does. Sniffer reads what your body leaves behind.

Wearables and connected health devices already track many of your body’s everyday signals.

But every day, your body leaves biological signals in the bathroom, via urine and stool.

Sniffer reads those signals passively, turning everyday bathroom visits into a new layer of health data.

Built for wellness today.
Ready when you need more.

Most days Sniffer is a wellness device: hydration, recovery, rhythms, changes from your normal. Nothing to wear, nothing to log.

But bodies don’t stay the same. When something changes and a doctor asks what’s been happening, most people have nothing to show. Sniffer does. The same device already produces a report in the format clinicians use, built from your own data over months, not from a single visit.
