The air in your home is shaping how you feel.

You spend ninety percent of your life indoors. The space around you is doing quiet, constant work on your sleep, your focus, your mood — and you've had no way to see it. Until now.

We measure our bodies. We measure our sleep. We measure our steps.
We've never measured the room.

The air carries CO₂ that dulls your thinking by 3pm, particulates from last night's dinner that linger past breakfast, humidity that decides how deeply you sleep, and a dozen other variables your body registers long before you do.

Leo is a single sensor and an interpretation layer that translates all of it into something legible — what changed, why it matters, and what to do about it. Continuous, residential, quiet.

i.
A single sensor
One quiet object on a shelf. Nothing to wear, nothing to charge.
ii.
Continuous reading
CO₂, particulates, VOCs, humidity, light, temperature — every minute.
iii.
Plain language
Not just numbers. A short read on what changed and why it matters.
iv.
Built for the home
Residential, not clinical. Designed to live where you live.
