Why most breathing exercises don't work
Most apps give everyone the same generic pace. But your ideal rhythm is unique to you, and it shifts with your stress, sleep, and time of day. If breathing exercises haven't worked for you, it's not you, it's the pace.
0%
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.
+0%
stronger body response at your personal rate
Match the pace to your body and your nervous system responds 18% more strongly. Same effort, deeper effect. That's why moonbird adapts to you every session.

Whatever you're working on, moonbird adapts
Stress
Ongoing tension that builds through your day. Moonbird finds the rhythm that actually downregulates your nervous system, personalized to your body. Two minutes during a break or before bed.
Focus
A short breathing session at the right pace resets your nervous system and sharpens your focus without the jitters. Use it between meetings or before deep work. Two minutes, and you're back.
Anxiety
Acute waves of worry or panic that hit suddenly. Hold moonbird in your hand and let the tactile rhythm ground you. The physical guidance gives your body something to follow when your mind can't focus.
Sleep
Your body is tired but your mind won't stop. Moonbird gives you a personalized pre-sleep breathing routine that shifts your nervous system into rest mode. No screen needed. Just hold it, close your eyes, and follow the rhythm into sleep.

Why the right breathing rhythm changes how you feel
Moonbird works by activating the vagus nerve, your body's main pathway between your brain and your organs, and the central nerve of the parasympathetic nervous system. 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. And why a generic pace doesn't cut it: the rhythm that activates your vagus nerve most effectively is unique to your body.

Common questions
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.
