Rest
Build a steadier wind-down
See how your body settles as you prepare for sleep.
Meet
Zeno One.
What if your wearable didn’t just track your health
—but taught you how to master it?
Three layers.
One calm signal.
A miniaturized sensor array and auricular interface work together, translating subtle
physiological patterns into practical, personal guidance.
Small enough to disappear.
Smart enough to stay useful.
A sharper picture of your state.
Optical heart-rate sensing, HRV trends, skin temperature and humidity are sampled together, so context is never reduced to a single number.
4 signals
Meaning, not another dashboard.
AI turns real-time and longitudinal signals into a clear daily picture — what changed, what may be influencing it, and what to try next.
1 clear plan
A gentle way back to balance.
Personalized auricular vagus nerve stimulation pairs with guided breathing to support rest, recovery and everyday regulation.
15 min
Your nervous system,
made legible.
The vagus nerve touches systems across the body. Zeno One helps turn those connections into a daily rhythm you can understand and influence.
Focus
Recognize overload sooner
Spot patterns that may signal when it’s time to reset.
Recovery
See the return to baseline
Follow recovery patterns across minutes, days and weeks.
Regulate
Respond when your body needs it
Pair personalized taVNS with guided breathing to support everyday regulation.
A useful answer,
not more noise.
Zeno One turns complex physiological signals into three simple steps: track, understand and act.

Technology for
the examined life.
ZenoWell takes its name from Zeno of Citium, who believed that a good life begins with attention to what we can understand and influence.
We built Zeno One on the same principle: notice your state clearly, meet it without judgment, and choose the next useful action.
Before you begin.
Clear information matters when the product is this personal.
What does Zeno One measure?
Zeno One combines heart rate, heart-rate variability, skin temperature and local humidity trends. The experience is designed for personal wellness and does not diagnose or treat a medical condition.
How is it different from a fitness tracker?
Most trackers stop at observation. Zeno One connects sensing, interpretation and guided nervous-system routines in one coherent experience.
Can I use it without the app?
Core sessions can begin from the device. The companion app adds trends, explanations and a personalized weekly plan.
When will Zeno One be available?
The first release is planned in limited quantities. Joining the early-access list saves your place and lets you choose your preferred finish before public release.
Know your signal.
Change your rhythm.
