Breethly vs. Moonbird

Breethly vs. Moonbird.

Both are handheld breathing tools, but they work differently. Moonbird is a tactile pacer that physically expands and contracts in your hand to guide your breath. Breethly reads your actual breath and coaches it with light and haptics, then turns each session into a trainable Nervous System Score.

The Short Version

A Pacer vs. a Coach.

Moonbird shows you a rhythm to follow. Breethly reads the rhythm you're actually breathing and coaches it.

Moonbird is a lovely, screen-free idea: a device that expands and contracts in your palm so you can breathe along by feel. If a simple tactile pacer is all you want, it does that beautifully.

Breethly closes the loop. Instead of only showing you a target, it reads the shape and rhythm of your breath at the source and coaches the next one, then rolls every session into a Nervous System Score so your practice compounds, not just repeats.

Which to Choose

Follow, or Train.

If you want the simplest possible nudge to breathe slower, a tactile pacer is a fine choice. If you want to know whether it's working, and watch yourself get better, Breethly's closed loop is the difference.

Breethly starts at $197, with founding pricing locked in for early reservations.

Questions, answered.

Moonbird is a tactile pacer that expands and contracts in your hand for you to breathe along with; it doesn't read your breath. Breethly reads your actual breath in real time, coaches it with light and haptics, and tracks a Nervous System Score so you can train and measure progress.

Moonbird is primarily a guide to breathe along with rather than a sensor that reads your breath at the source. Breethly's distinguishing feature is that closed feedback loop: it responds to what you're actually doing.

If you struggle to keep a slow, steady rhythm on your own, a handheld tool helps a lot. The question is whether you want a simple pacer to follow (Moonbird) or a coach that reads your breath and helps you improve over time (Breethly).
