HRV Breathe - Breathwork

Most breathing apps ask you to take it on faith.

HRV Breathe gives you three ways to look at your own practice: your heart rate variability as recorded in Apple Health, a one-tap check-in on how you actually felt, and - on Apple Watch - the live rise and fall of your heart rate while you breathe.

FIVE TECHNIQUES, EACH FOR SOMETHING DIFFERENT

Resonance (5-7 BPM). The default. Around six breaths a minute is the slow, even pace most people settle into when they deliberately wind down.

Box (4-4-4-4). Equal inhale, hold, exhale, hold. Metered attention when you need composure.

4-7-8. A long, weighted exhale. Built for the end of the day.

Extended Exhale. Any ratio where the exhale runs at least twice the inhale. Fully configurable.

Cyclic Sighing. Two inhales through the nose, then one long exhale. Short and structured.

LIVE PULSE ON APPLE WATCH

During a session your Watch streams your heart rate and shows how far it swings as you breathe - your heart speeding up on the inhale, slowing on the exhale. The app displays it as recorded, without scoring or interpreting it.

The workout session behind it is always discarded. Nothing is written to Health.

FIND YOUR RESONANCE

Slow breathing is not one speed for everyone. The guided exercise paces your Watch through five stages, from 7.0 down to 5.0 breaths per minute, and shows the heart-rate swing recorded during each. You choose which pace to set the pacer to.

MULTI-DAY PROGRAMS

HRV Bootcamp, 7 days. Resonance breathing that eases from 6 BPM toward 5 BPM as the slower pace becomes comfortable.

Sleep Wind-Down, 5 nights. Evening 4-7-8 and extended-exhale sessions before bed.

Morning Activation, 5 mornings. Box breathing, then resonance.

Gentle Start, 14 days. A deliberately slow ramp with no breath holds at any point, for anyone who finds standard breathwork too intense.

ALSO IN THE APP

The physiological sigh, a 30-second exercise you can do anywhere. The BOLT breath-hold timer, a simple self-recorded number you can repeat over time. Daily goals and streaks. Widgets, Siri and the Action Button. A Live Activity on your lock screen. Pocket mode, which paces you through haptics alone so you can put the phone away.

A full Apple Watch app that works offline and syncs back to your iPhone.

PRIVATE BY DEFAULT

No account, ever. Your sessions sync across your own devices through iCloud, never our servers. HRV is read from Apple Health and stays on your device. Writing Mindful Minutes and State of Mind back to Health is opt-in and off until you turn it on.

TRY IT FREE FOR 7 DAYS

Everything above is included in the trial, on iPhone and Apple Watch. After it ends, HRV Breathe is $4.99/month or $29.99/year, and a one-time Lifetime purchase is also available. Subscriptions renew automatically unless cancelled at least 24 hours before the period ends; manage them in your App Store account settings.

IMPORTANT - NOT MEDICAL ADVICE

HRV Breathe is a general wellness and relaxation app. It is not a medical device. It does not diagnose, treat, cure or prevent any disease or condition, it does not provide medical advice, and no reading it shows should be used to make a medical decision. Seek the advice of your physician in addition to using this app and before making any medical decision. Heart rate and heart rate variability are shown as recorded by your own Apple devices in Apple Health.

Breath holds are not for everyone. If you are pregnant, have a cardiovascular or respiratory condition, or have a history of fainting, talk to your doctor before trying them. Never practise breath holds in water or while driving. Stop if you feel dizzy or unwell.
