Your breath. Every night.
Measured.

A nasal ring that measures real airflow directly during sleep — at home, without clinic visits or complex equipment.

Understanding Sleep Apnea

What is
sleep apnea?

Sleep apnea is a condition in which breathing repeatedly stops during sleep. These interruptions can happen dozens or even hundreds of times per night — often without the person being aware.

The result is a night that doesn’t restore you. People wake up exhausted, as if they never slept, and stay sleepy through the whole day — and over time their quality of life suffers.

Type 01 · OSA

Obstructive

The airway is physically blocked — the tongue or soft palate collapses against the throat. The most common form, typically associated with snoring.

Type 02 · CSA

Central

The airway is open, but the brain fails to send the signal to breathe. A neurological issue — the body simply does not attempt to breathe for a period.

Type 03

Mixed

A combination of both obstructive and central events in the same person. Often one type transitions into the other within a single episode.

The airway during sleep

What actually happens

Normal breathingOpen

Air moves freely through an open airway, breath after breath.

SnoringNarrowed

The airway narrows and the tissue vibrates. Airflow is reduced, but not stopped.

Obstructive apneaBlocked

The airway closes. The chest keeps trying to breathe, but no air gets through.

Central apneaNo signal

The airway is open, but the brain does not send the signal to breathe.

Simplified illustration.

The type of apnea can be determined once — through a sleep study. What matters most after diagnosis is tracking events every single night and understanding how they change based on your habits and routines.

The Solution

Direct airflow.
Every night.

A nasal ring worn during sleep that measures actual nasal airflow and syncs data to your phone.

Direct Airflow Measurement

Real nasal airflow sensors — not heart rate proxies. Measures airflow directly, unlike smartwatches or fitness rings.

All-Night Comfort

Lightweight ergonomic design. Charges in a compact case.

How It Works

Measure. Improve.
Share. Together.

Eight steps, one loop — wear the ring, see your data, try something new, track the change. Sleep apnea management reimagined as a positive feedback cycle.

  1. We try something

    Take one action to improve your sleep and health.

  2. Measure

    The ring measures airflow and detects apnea during sleep.

  3. Check results

    See your apnea results and sleep insights in the app.

  4. Try & improve

    Try different things that help you feel better: exercise, a healthy lifestyle, meditation.

  5. Measure again

    Track the changes every night and see what actually works.

  6. Share

    Share your results, your experience and what helped.

  7. Community solves together

    Learn from each other and find the best solutions.

  8. Fix the problem

    Keep improving until you reach better sleep and a healthier life.

The Story

Built by someone
who lives with it

After COVID, I started waking up exhausted every single day. I was diagnosed with sleep apnea — and then left to figure the rest out on my own.

I went through sleep labs, polysomnography rigs, CPAP masks, clip-on oximeters, smartwatches. Nothing was designed for daily use. Nothing let me track what actually made a difference night to night.

So I built it myself. Not as a researcher. As a patient who needed it.

"Sleep apnea is highly individual. There is no single solution — each person must find what works for them. They need data to do that."

Project Progress

Where we are
right now.

We are building in the open. This page is updated as the project moves forward.

Concept & Feasibility In Progress

Problem validation, product concept and initial hardware exploration.

Prototype 3 and 4

What we built

We built a re-flashable debug PCB and placed it inside a temporary housing to test the detection theory. This is not a final product — the housing and form factor are for testing only. The next step is a new PCB and a real in-nose ring enclosure.

The first prototype is quite big — but right now what matters is data and debugging, not size. Making it smaller comes next.

Debug PCB — airflow sensor and Bluetooth module

Debug PCB — actual size ~3 cm

New — women's design

From prototype to final product, smaller size for women

We are also working on a smaller version of the ring, sized for women.

Current focus

  • 1.Patent search started — protecting our core approach.
  • 2.Primary goal: build our own dataset for open public research and analysis.
  • 3.Exploring MEMS sensors. Current focus: reliable data transport to the cloud and connecting AI to the dataset. MEMS microphones look particularly promising.
  • 4.Next step: finalising sensor approach before moving into beta testing.
  • 5.Dataset scaling during beta testing.
