stronger HRV response when breathing at your personal pace versus the standard one.

Breathing at your right pace makes your body respond more.

Most breathing apps use one pace for everyone. But our research across 269,764 sessions shows that about 3 in 4 people respond best at a pace that isn’t the standard 6 breaths per minute. Breathing at your personal pace makes your heart and breathing work together 18% better. Moonbird reads your pulse and learns yours over your first weeks of use.

Moonbird helping with stress
Stress

The calm you can carry with you.

“Within seconds, I feel the tension melt away. My breathing has become deeper, steadier, and more regular.”

Francisca·2025
Moonbird helping with sleep
Sleep

Fall asleep holding it. Wake up without it.

“Since I got my moonbird, I no longer have to take sedatives to sleep. It never fails to calm my anxiety and help me fall asleep.”

Aileen M.·2023
Moonbird helping with anxiety
Anxiety

On-demand relief. No appointment needed.

“I’ve used it during stressful meetings, family parties, and in the middle of the night when anxiety hits hardest. It just works.”

T. Rodriguez·2025
Moonbird helping with children
Children

Bedtime without the battle.

“Our daughter sleeps with moonbuddy every night. Our oldest son, whose brain just doesn’t stop, uses the breathing to enter a calm, almost meditative state.”

Moonbird helping with focus
Focus

Set the tone before the day sets it for you.

“I use it in the morning when I have challenging times at work or a lot ahead of me. It helps set a peaceful tone for the day.”

Salma AlSayyad·2023
Moonbird helping with racing thoughts
Racing thoughts

Silence the noise. Just breathe.

“It helped me empty my mind. This in contrast to mindfulness and meditation which do not prevent my mind from being distracted with endless thoughts.”

Carine·2024

How does it work?
Four simple steps.

01

Turn it on.

Put your thumb on the sensor and give moonbird a gentle shake. It’s ready when you are.

02

Breathe along.

Feel how it expands and contracts in the palm of your hand. When it expands, breathe in. When it contracts, breathe out. No screen, no counting, just follow the rhythm.

Pair with the free app for more.
03

See the impact.

Open the app to see real-time biofeedback on your heart rate and HRV. Watch your nervous system respond as you breathe.

04

Let it learn you.

Aura, your AI breathing coach, reads your data in the first 30 seconds and suggests a personalized breathing rhythm. The more you use it, the smarter it gets.

Screen-free when you breathe.
Smart when you need it.

Moonbird works beautifully on its own. The app adds coaching, data, and personalization.

Aura, your AI coach

Aura checks in before you start, picks the right protocol, and speaks in a voice that knows what your last session did. If your HRV says you are braced, she slows down. If your mind is racing, she lengthens your exhale.

Not a library of recordings. A coach that gets better the longer you use her. She remembers the Tuesday you were wrecked, and she is there the next time it happens.

Real-time biofeedback

Open the app mid-session and watch your heart rate variability climb in time with your exhale. A live coherence score tells you the moment your nervous system locks in.

It is the first time most people see, literally see, their own breath calming their body. That feedback loop is what trains the skill, so you can find the same state later without looking.

Your data, your progress

Every session leaves a trace: duration, average HRV, coherence, mood, and how you felt in one tap after. Trends surface week over week, so streaks mean something and so do the breaks.

Months in, the app can point at the pattern your body already lives by, the time of day you breathe best, the week you plateaued, the month you turned a corner.

Connects to what you already use

Pair with Oura, Apple Health, or Google Health Connect and your breathwork lands alongside your sleep, recovery, and activity. The app looks at all of it together.

So when a session lands especially well, you can see why: a ring score that crossed a threshold, a stretch of better sleep, a Monday morning that finally went right.

The most intuitive way to practice breathwork
uses the power of touch.

Touch is how we calm each other. A hug, a hand on the shoulder, a child holding a teddy bear. Moonbird uses that same instinct to guide your breath: it expands, you breathe in; it contracts, you breathe out. No screen, no counting, just your hands.

Questions you might have.

Moonbird is a handheld breathing coach. It expands and contracts in your hand, and you breathe with it: in as it expands, out as it contracts. You can use it screen-free, or pair it with the app to see how your body responds. The app shows your heart rate and heart rate variability changing in real time as you breathe.
No. The device works on its own as a tactile coach. The app adds real-time biofeedback, Aura coaching, insights, and wearable integrations with Oura, Apple Health, and Whoop. The basic version of the app is included with your device. Premium, with Aura and advanced insights, is available as a monthly or yearly subscription.
Aura is the AI breathwork coach inside the new moonbird app. Before each session, she asks how you’re doing, in your own words, and builds the session around your answer. During the session, she adapts. If your moonbird device is connected, she reads your pulse in real time: if your heart rate isn’t dropping she slows the pace, if you’re settling quickly she goes deeper. Afterward, she remembers what worked, so each session builds on the last. Aura is part of the premium version of the app.
The moonbird app has two tiers.
  • The basic version comes with your device: a library of breathing exercises, exercise customization with your moonbird, wearable integrations, and basic insights into your session data and trends. No subscription needed.
  • Premium unlocks personalization: Aura, your AI breathwork coach; your personalized breathing pace, found over a 7-day onboarding and refined every session; and advanced insights like detailed HRV breakdowns, breath-heart synchrony, and recovery scores. Premium starts with a 7-day free trial, then auto-renews to a monthly or yearly plan.
Moonbuddy is a cuddly breathing companion for children. It rises and falls like a calm belly, so kids naturally follow its rhythm. Your child holds it, breathes along, and their nervous system settles. It offers four breathing rhythms, with pediatrician-informed pacing, no lights, no alarms, and no app required. Same idea as moonbird, shaped like a friend.
Moonbird is for adults who want to sleep better, feel less stressed, or relax more easily. Moonbuddy is for children who find it hard to calm down at bedtime. Therapists and clinicians also use moonbird alongside cognitive behavioral therapy (CBT), and it’s used in hospitals and schools, where studies have shown benefits for relaxation, emotional regulation, and sleep (Pleumeekers, E., 2024).
Many people feel a difference after their first session. Others need a little time to get used to breathing with the device in their hand. The device comes with a 30-day trial, which is enough time to feel whether it works for you.
If you’ve tried meditation or breathing techniques before, you know how hard it is to hold your focus. Moonbird gives you something to follow. The tactile rhythm keeps you with the breath, so the practice is easier to stay with and more effective. Unlike apps and audio guides, moonbird works screen-free, guided by touch, while the app adds biofeedback when you want it. Peer-reviewed studies show moonbird can help improve sleep and reduce stress, and several insurers reimburse it. Try it for 30 days, and if it’s not for you, send it back.
You can try moonbird or moonbuddy for 30 days. If you don’t feel the benefit, return it for a full refund, and we cover the return shipping.
In the US, you can buy moonbird with your HSA/FSA funds. In the EU, providers including Zilveren Kruis, Menzis, ONVZ, CM, and Helan reimburse part of the cost of moonbird and moonbuddy. More partners join regularly, so check our latest updates for the current list, or ask your insurer directly.
Many do. We work with clinicians across anxiety, trauma, sleep, and pediatric care, and we run a professional program with bulk pricing and training.
