Why most breathing exercises don't work

Meditation wants sustained attention. Breathing exercises want you to count and hold the pattern. The apps want you to find your phone, open them, and choose. That is all executive function, and it clocked out with the workday. Moonbird is built for brains that hate counting.

of people have a personal breathing rate
The standard 6 breaths per minute isn't right for most bodies. Your optimal rhythm depends on you, which is why generic pacing rarely works.

How it works

What the app adds

Set it once, then leave your phone out of it. The evening ritual is just the device, shake and follow, phone in another room. The app is where you tune moonbird to your rhythm and, if you want proof, watch your heart rate come down.

Whatever you're working on, moonbird adapts

After work

Your body is spent, but your head is still going. This is the reset for the hour after the day ends. Shake it, follow, and let the noise come down.

Overstimulated

A normal day stacks up in small layers, the open office, the supermarket, the group chat, and it all lands at your front door. Moonbird is the way back down, before you reach for the wine or the scroll.

Wired but tired

Exhausted and restless at the same time. When you can't sit still and can't switch off, moonbird gives your hands something to hold and a pace to breathe to.

The masking crash

After a day of managed faces, the social battery is empty. A few minutes with moonbird before the evening asks anything more of you.

Why the right breathing rhythm changes how you feel

Moonbird works by activating the vagus nerve, the parasympathetic pathway between your brain and your organs. When you breathe at the right rhythm, it switches on: heart rate drops, cortisol falls, and your body shifts from fight-or-flight into rest-and-restore.

That's why the right breathing rhythm can change how you feel in minutes.

One honest note for this crowd: we make no ADHD or autism claims, and there is no trial of breathing devices in ADHD. What we can say is that slow breathing calms the body, and moonbird makes it doable for brains that hate counting.

It doesn't replace what already works. It joins it.

Your headphones and earplugs are for surviving the noise. Your weighted blanket holds you. Your medication does its job through the day. Moonbird is the piece for the evening after, when the day is done but you are not down yet. Keep all of it. This is the active one.

Common questions

Free breathing needs counting, remembering, and focus, the exact thing that is gone by 7pm. Moonbird counts for you. You follow, it leads.

What is well documented, in general adults, is that slow breathing calms the body's stress response. Making that easy to actually do is what moonbird is built for, and it is why plenty of ADHD and autistic adults keep one on the sofa arm. Our own research is on sleep (Vermeylen 2022), stressed adults (Honinx 2025), and a case-study paper on moonbird in CBT (Pleumeekers 2024) where one of six participants was an autistic adult.

Maybe, which is why there is a 30-day money-back guarantee. It tends to stick because it lives where your evening happens, the sofa arm or the coat hook, and some people need about a week before it clicks.

No. Your medication does its job. Moonbird is for the evening hours, alongside whatever else works for you.

No. Moonbird works as a standalone device with guided breathing exercises. The basic app adds customization, insights, and wearable connection. Premium adds personalized pace and interactive coaching.

The basic app gives you everything to get started: breathwork content, a library of exercises, exercise customization, wearable connection, and biofeedback and insights. The premium app adds three things: Aura, your AI breathing coach who guides and responds to you in real time; a personalized breathing pace that adapts every session to your body; and advanced insights with deeper HRV analysis, recovery scores, and a prediction of how well you will sleep tonight.

A learning process discovers your optimal breathing rate, ratio, and what moves the needle most for you. It provides distinct recommendations for relaxation, focus, and sleep, and every session adapts over time as it learns more about your body.

Most sessions are 2 to 10 minutes. In our data, sessions as short as 2 minutes show significant mood improvement. What matters most is breathing at the right rate, not how long you breathe.

Yes, you can cancel anytime. Your subscription will remain active until the end of the current billing period, and you'll keep full access to the basic app with all its features after that. There's no lock-in.
