About this app

Zephyr gives you a pace to follow, so a few minutes of slow breathing actually happens instead of staying something you meant to do.

Open it, pick a technique, breathe with the pacer. No account, no sign-up, no ads.

41 BREATHING EXERCISES, SORTED BY WHAT YOU NEED
Seven collections — Foundational & Calm, Sleep & Relaxation, Stress & Anxiety, Focus & Performance, Energy & Performance, Pranayama & Advanced, and Family — so you find a breathing exercise by how you feel, not by its name.

Free to start: Box Breathing, 4-7-8 Breathing, Diaphragmatic Breathing, Triangle Breathing, Anxiety Relief, Panic Relief, Calm, Refresh, Walking Breath and Kids Breathing.

With Zephyr+: Alternate Nostril, Coherent Breathing, Resonance Breathing, Pursed Lip Breathing, Kapalabhati, Bhramari, Sitali, Power Breathing, Athlete Performance and more.

A PACER YOU CAN FOLLOW WITH YOUR EYES CLOSED
An orb that expands and contracts with your breath, optional spoken cues, and a haptic tap on each phase change. Turn any of them off and the app remembers.

KEEPS GOING WHEN YOUR SCREEN DOESN'T
Start a session, put the phone in your pocket, and it keeps running. Pause and resume from your lock screen or the notification shade.

YOUR BREATH SCORE
A free breath-hold test scores your result out of 100 and tracks it over time, so you can see whether your breathing is changing.

MIX YOUR OWN AMBIENT SOUND
Fourteen channels with a separate volume for each, so you build the exact background you want and keep it playing under a session. Rain, Fireplace, Birdsong and Brown noise are free.

GUIDED PROGRAMS
Seven multi-day programs: 7 Days to Calm and Anxiety Reset are free, with Better Sleep, Stress Master, Morning Energizer, Athlete Performance and 21 Days of Power Breathing in Zephyr+.

AN AI COACH THAT KNOWS YOUR NUMBERS
Ask about a technique, a pattern, or what your Breath Score means. It sees your recent test results, so the answer is about your breathing rather than breathing in general.

WHAT'S FREE
Thirteen techniques, two programs, four ambient channels, the full breath test, five sessions a day and five coach questions a day.

WHAT ZEPHYR+ ADDS
All 41 techniques, all seven programs, all fourteen ambient channels, and unlimited sessions and coaching. Monthly, yearly, or a one-time lifetime purchase.

NO ACCOUNT REQUIRED
Nothing to sign up for. Your sessions, streaks and history stay on your device.

Zephyr is a wellness app, not a medical device, and is not a substitute for professional care.

What’s new

Lock-screen controls: pause and resume a session from your lock screen or notification, and audio keeps playing when your phone is pocketed.

Power Breathing: no longer stalls in the background, pauses and resumes properly, and each spoken cue plays to the end instead of being cut short.

Breath test: times your real hold, so your score is accurate.

Sound, voice and haptics settings are now respected throughout Power Breathing.

Optional breath cues in the pace trial.
