02 / Why We Win

A New Standard for
Clinically Guided Support

Designed to meet patients where they are — with guidance that fits naturally into daily life.

Clinically Validated

Peer-reviewed publication in JMIR demonstrating real outcomes. The only perinatal breathwork device with published clinical evidence.

Designed for Perinatal Care

Built specifically for postpartum and high-intent populations. Tested at Women & Infants Hospital with postpartum participants.

Passive Airflow Guidance

No learning curve — the device guides breathing automatically through patent-pending dual-nozzle airflow. The body follows. No added cognitive load.

Measurable Biofeedback

Measurable results that reinforce engagement and support sustained use.

Real-World Adherence

In our clinical study, moms used Just Breathe while holding their baby — because it's an oral device, their hands stayed free. Designed for daily life, not clinical conditions.

03 / The Device

The first passive clinical breathwork device, engineered for real-world use

A compact oral wearable with patent-protected technology and dual-nozzle airflow cues. Clinically guided breathing with measurable, real-world results.

04 / How It Works

Guided Breathing, Without the Guesswork

Most breathing exercises fail because they require active effort. Just Breathe removes that burden entirely — the device does the work for you.

Inhale and exhale airflow explainer illustration
1

Airflow guides every breath

Precision airflow cues naturally shape your inhale and exhale rhythm. The physics of the device do the guiding — your body simply follows.

2

No counting. No timing. No focus required.

Unlike apps and audio guides, there's nothing to track or remember. Breathing regulation becomes automatic — even while feeding, working, or resting.

3

Real-time stress & recovery feedback

The companion app reads your HRV and breathing data live, showing stress trends and recovery progress in the moment — not just after the session.

4

Lasting physiological resilience

Consistent use recalibrates your nervous system over time. Clinical participants showed measurable HRV gains — a biomarker for long-term stress resilience.

05 / Companion App

Real-time biofeedback, every session

Bluetooth-connected app tracks HRV, respiratory rate, and adherence metrics in real-time. Clinical-grade biofeedback with measurable, guided results every session.

07 / Market Focus

Starting Where the Need Is Highest

We're not trying to solve all anxiety. We're starting with the population that needs a solution most urgently — and building the evidence base to expand from there.

Initial Focus

Postpartum & Perinatal Anxiety

1 in 5 mothers experience postpartum mood disorders. Current solutions require active effort that new parents simply don't have. Just Breathe is the first device built specifically for this population — clinically tested, passively delivered, and designed around the constraints of new parenthood.

Expansion Roadmap

Corporate Wellness

Scalable stress management for high-burnout environments. No training required.

Chronic Condition Support

Adjunct tool for patients managing anxiety alongside chronic illness or long-term recovery.

General Anxiety Management

Broad consumer market for daily stress regulation — the device works for anyone.

08 / Validation Data

Over 300 women included across clinical and validation studies

Clinical study and independent market research conducted with pregnant and postpartum women. The data validates both the need and the solution.

11 / Common Questions

Frequently asked

Everything you need to know about Just Breathe, from clinical evidence to how to get yours.

Is it clinically proven?
Yes. Just Breathe was validated in a peer-reviewed clinical study published in JMIR (Journal of Medical Internet Research) in 2026. The study was conducted with postpartum women at Women & Infants Hospital, affiliated with Brown University. 88% of participants reported high satisfaction. Read the full study.
How long does it take to work?
Most participants report measurable anxiety reduction within 3–5 minutes of use. The device guides breathing passively through airflow cues — no active focus required. Clinical participants demonstrated measurable HRV improvement within a single session in the peer-reviewed JMIR study.
Is it safe during pregnancy?
Yes. The device was specifically designed and tested with perinatal women. The clinical study at Women & Infants Hospital included pregnant and postpartum participants. 94.2% of surveyed women ranked pregnancy and postpartum safety as their #1 priority, and the device was built to meet that standard.
How is it different from breathing apps?
Breathing apps require your attention, your hands, and a screen. Just Breathe is completely passive and screen-free. You place the device in your mouth and your body follows the airflow cues automatically - no counting, no screens, no active focus needed. It works while you nurse, rock the baby, or rest.
What does it cost?
The expected retail price is $299, which includes the device, a premium carrying case, and the companion app with HRV tracking. Waitlist members will receive exclusive early access pricing. Join the waitlist to lock in your spot.
How do I get one?
We're in final clinical development and pre-commercial production. Sign up for the waitlist to be first in line when we ship. Waitlist members get early access, launch pricing, and real-world outcomes updates as we move from clinical validation to commercial availability.
11 / Market Opportunity

A Large, Underserved Market

700K+
Women affected annually

Perinatal mood and anxiety disorders affect over 700,000 women each year in the U.S. alone - making PMAD the most common complication of pregnancy, yet among the least addressed.

Low Adherence
The gap no one is closing

Current solutions - breathing apps, CBT programs, medication - suffer from chronically low adherence and deliver no measurable, real-time outcomes. Women are prescribed tools they never use.

Defining a new standard

Just Breathe is first to combine passive airflow guidance, real-time HRV biofeedback, and peer-reviewed clinical validation specifically for perinatal care - a category no one has owned.
