A Passive Breathing Device Built for the Reality of New Parenthood

Name: Just Breathe
Brand: Just Breathe
Price: 299.00 USD
Availability: PreOrder

Hands-free. Screen-free. Studied with postpartum mothers at Women & Infants Hospital and published in peer-reviewed literature.

83% satisfaction • 25% HRV increase in a single session

83% satisfaction measures acceptability — whether participants found it usable — not symptom improvement. 25% HRV increase in a single session confirms the device produces the intended physiological effect; HRV is a biomarker, not a clinical outcome.
Study design: single-arm prospective cohort, n=40, postpartum. No control group.

01 / The Problem

The Gap Between
Instructions and Outcomes

→ Patients are often told to "just breathe" — but without support, guidance, or time, it's difficult to translate that advice into real relief.
→ Postpartum anxiety and stress impact over 20% of new mothers
→ Existing tools require active attention, screens, or scheduled sessions that new parents simply don't have
→ The result is continued stress, anxiety, and unnecessary suffering during a time when support matters most.

02 / Why We Win

A New Standard for
Clinically Guided Support

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

Built for Hands That Are Already Full

Apps, CBT programs, and meditation all fail the same way — they need your attention, your hands, and a screen, exactly when you have none. Just Breathe is passive and screen-free. In our study, mothers used it while holding their newborn.

Designed for Postpartum 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.

HRV and Respiratory Rate Tracking

Track physiological signals that help describe each session without presenting them as clinical outcomes.

Peer-Reviewed Feasibility Study

A published single-arm prospective feasibility cohort with 40 postpartum participants at Women & Infants Hospital.

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

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.

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.

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.

Track breathing signals

The companion app tracks HRV and respiratory rate; these are physiological measures, not clinical outcomes.

05 / Companion App

HRV and respiratory rate tracking, every session

The Bluetooth-connected app tracks HRV and respiratory rate during each session, alongside adherence metrics.

06 / What the Study Showed

What the Study Showed

A single-arm prospective postpartum feasibility cohort with 40 completers at Women & Infants Hospital. The results were published in JMIR Formative Research.

What We Haven't Proven Yet

Our study shows the device is usable, well-tolerated, and produces the intended physiological response. It does not yet show that Just Breathe reduces anxiety more than an app, a paced-breathing timer, or usual care.

That is what we are testing next: a randomized controlled trial with 120 postpartum participants at Women & Infants Hospital, with GAD-7 as the primary outcome. We will publish the results either way.

83%

Satisfaction

33 of 40 postpartum participants were mostly or very satisfied with the device, a measure of acceptability rather than symptom improvement.

25%

HRV Improvement

A 25% increase in mean HRV was observed in a single session; HRV is a biomarker, not a clinical outcome. The study found a minimal paired effect size.

Peer‑Reviewed

Published Literature

Published in JMIR Formative Research as a single-arm prospective postpartum feasibility study.

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 a passive device designed around the constraints of new parenthood and studied in a peer-reviewed feasibility study.

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

40 postpartum participants in our published feasibility study, plus 260+ pregnant and postpartum women surveyed in market research.

The published feasibility study included postpartum participants only. Separate market research surveyed pregnant and postpartum women about needs and preferences; it does not validate safety or clinical efficacy.

11 / Common Questions

Frequently asked

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

What has been studied so far?

A peer-reviewed feasibility study with 40 postpartum participants at Women & Infants Hospital, affiliated with Brown University. It was a single-arm cohort — no control or placebo group — so it shows the device is usable, well-tolerated, and produces a measurable physiological response. It does not show it outperforms other approaches. A 120-participant randomized trial is planned to test that.

How long does it take to work?

The device guides breathing passively through airflow cues — no active focus required. The published feasibility study assessed a 3-minute breathing cycle but did not establish symptom improvement.

Can I use it during pregnancy?

Our published study was conducted with postpartum participants at Women & Infants Hospital. We have not studied the device during pregnancy and make no safety claims for pregnant users. Talk to your OB or midwife before using any new device.

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.

12 / 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.

New Category

Defining a new standard

Just Breathe combines passive airflow guidance with HRV and respiratory rate tracking for postpartum recovery — a product category still taking shape.
