Breathe better. Sleep deeper. Stress less.
Moonbird is your personal breathing coach. Open the app, follow the guidance, and let your breath settle your body and mind. Everything you need to build a real breathing practice is in the app, whether or not you have the moonbird device.
This app is not a medical device and does not diagnose, treat, or prevent any condition.
Why most breathing exercises don't stick
Most apps give everyone the same pace. But your ideal breathing rhythm is your own, and it shifts with your stress, your sleep, and the time of day. Breathe at the wrong rate and it feels like nothing happened, so people give up. The real fix is finding the right pace, and that's what moonbird does for you.
Personalized to you
Moonbird shapes each session around your goal, whether that's calm, focus, or sleep. Aura, your AI breathing coach, interacts with you and adapts in real time, with spoken guidance and ambient soundscapes matched to your mood, so each session helps you fully switch off.
What you get in the app
A full library of breathing exercises with spoken guidance. Static and custom exercises you can shape yourself. Aura, your AI breathing coach, with personalized coaching around your preferences and goals on premium. Wearable connections for Oura and Apple Health. See how your breathing lines up with your sleep, stress, and recovery data over time.
Do more with the moonbird device
Have the moonbird device, or thinking about it? Hold it in your hand and it sets your breathing rhythm through gentle movement. Breathe in as it expands, out as it contracts.

I can’t believe how hard it is to just use the app to do the brief exercise for just 20 minutes. It always stopped at one minute when I try to fall asleep please fix this.
Love the idea, but full of bugs
Macaholic262
I have the moonbird hardware which I like a lot, and the idea of getting all this data and having an AI guided session is also amazing - but the whole app is just full of bugs and the developers don’t respond to bug reports. Feels like this was vibe coded with no QC. Hope it gets better but wouldn’t recommend the subscription at all right now.
Doesn’t sync
NickR8
The sessions from the device don’t sync to the app correctly. I like the device but the software sucks
- Now available in French
- Breathing cues stay audible in every session
- More reliable sync of offline sessions
