How does moonbuddy work?
Just like the moonbird, the moonbuddy offers tactile guidance for breathing exercises. Its belly expands and contracts, allowing your child to breathe along calmly.
The moonbuddy has three different breathing rhythms. With just one button, you can turn on the device and switch between exercises. After four minutes, it stops automatically, so your child doesn’t go on for too long. Charging is easy with a cable, so no external batteries are needed.
The interchangeable sleeves make the moonbuddy extra fun! We currently have two versions: Bibi the bird and Barry the bear, with more characters on the way.
The best part? The moonbuddy is completely app-free, so your child isn’t tied to a smartphone.

- Green light: 8.5 breaths per minute (3.5 s inhale, 3.5 s exhale)
- Blue light: 9 breaths per minute with a pause and a longer exhalation (2.8 s inhale, 0.4 s pause, 3.5 s exhale)
- Red light: 10.5 breaths per minute (2.8 s inhale, 2.8 s exhale)
- Yellow light: 6 breaths per minute (5 s inhale, 5 s exhale)
The duration of an exercise is set at 4 minutes. After this, the moonbuddy shuts itself off automatically. -
