Coherence

What It Is

Your breath is the fastest way to change how you feel. A specific rhythm, 5.5 seconds in, 5.5 seconds out, helps bring your heart rate and nervous system into alignment within minutes. It's called coherence breathing, and decades of research back it up.

Coherence is an app that makes this effortless. Open it, pick a session, and breathe. No tutorials. No clutter. Just a clean interface that shifts your state. Whether you need to focus, de-stress, energize, or fall asleep.

Beyond solo sessions, we built real-time synchronized breathwork. At coherencebreath.com/sync, anyone can join a live session with people around the world. No app download required. Everyone follows the same rhythm at the same time.

The Story

Coherence was founded by two brothers, Jack and Nick Sweeney.

Growth & Breathwork

Nick had been teaching breathwork privately and helping people regulate stress and improve performance through a method he called the Vortex Breath. It went viral, reaching millions. But working 1:1 didn't scale, and he had a bigger vision: one million people breathing together.

Jack saw an opportunity to turn that viral method into something structured, repeatable, and accessible to anyone. Over Christmas 2024, they decided to go all in.

The core belief was simple: if you're opening a breathwork app, you don't want confusing interfaces and upsells. You want to breathe and feel better immediately. Every design decision came from that.

Since launch in February 2025:

Why It Matters

Most people don't realize they can change how they feel in under a minute. Without substances, screens, or external stimulation. Just by changing the way they breathe.

That's powerful on its own. But when thousands of people do it together, physiology shifts at scale. Stress drops. Focus deepens. Nervous systems align. The effect is amplified far beyond what any individual can create alone.

Our goal is measurable global coherence.
