Your personal environment insights matter

You track your heart rate, HRV, and sleep stages — but your body doesn't recover in a vacuum. Your environment matters just as much as your metrics.
Indoors

CO2 — the silent sleep killer: high levels mean poor rest, even if you don't notice it.

Temperature and humidity — the difference between waking up fresh and waking up groggy.

&
Outdoors

Dust PM2.5/PM10 — known when the air outside is actually safe to let in

Noise — find out what's really waking you up at night

Temperature and humidity — the full picture of what's happening beyond your walls

All of this helps you make smarter decisions: when to work out, when to open a window, when to switch on the air purifier, and how to finally get the sleep your body deserves.

New way of flexible manufacturing

We have designed and tested unique 3D-printed cases to perfectly fit our hardware inside. This allows us to offer a wide range of colors and even new designs in the future. All models are open-source, so if you have DIY experience and a 3D printer, you're welcome to print and swap the case yourself.
