Coheria: Cardiac Coherence
Breathing to calm stress
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Breathe better. Feel calmer. In just a few minutes a day.
Coheria is a breathing companion built around cardiac coherence — a simple practice studied for its effects on the nervous system and the stress response. No theory, no clutter: open the app, follow the gentle on-screen wave, and let your breath slow down.
— HOW A SESSION WORKS —
A calm shape expands as you breathe in and shrinks as you breathe out, setting an easy pace of six breaths per minute. You just follow it. Within a minute or two your breathing lengthens, your shoulders drop, and your mind has one quiet thing to rest on. No voice, no talking, no distraction — only a clear visual rhythm to follow.
— WHY CARDIAC COHERENCE —
Breathing slowly and evenly at about six breaths per minute helps your heartbeat and your breath fall into sync. It's a short, repeatable way to down-shift out of stress and into a steadier, calmer state — before a meeting, after a hard day, or any time you need to reset.
— THE 365 METHOD —
The practice works best as a daily rhythm: 3 sessions a day, 6 breaths a minute, 5 minutes each. Coheria is built entirely around this cadence and makes it effortless to keep, with gentle morning, noon, and evening reminders you can move to fit your day.
— A JOURNEY THAT ADAPTS TO YOU —
New to breathwork? Start with the Discovery journey. Three gentle levels ease you in, beginning with sessions as short as a minute. After each one Coheria asks how it felt and adjusts — slowing down if it was hard, going deeper when you're ready — until the full cardiac coherence rhythm feels natural.
— SOUNDS THAT SET THE MOOD —
Wrap your practice in a soothing atmosphere — a forest breeze, soft rain, a crackling fireplace, or deep underwater calm — and add a subtle cue like a singing bowl to mark each breath, or breathe in complete silence. Sound can fade out gradually, guiding you at the start and slipping away as you settle.
— A HABIT THAT STICKS —
Coheria quietly tracks your streak, total minutes, and active days, so your progress feels visible and rewarding. A single session keeps your day, and built-in grace days protect your streak when life gets busy — consistency that encourages, never pressures.
— MADE YOUR WAY —
Create your own sessions with a custom inhale, hold, and exhale rhythm and duration. Switch to dark mode for evening practice. Available in English, French, German, and Spanish, with no account required — your practice stays private on your device.
Coheria is free to use, with no subscription. An optional one-time Coheria Pro purchase simply adds extra premium soundscapes and sound cues for those who want more atmosphere.
Take five minutes. Your body will thank you.
