A breath for
every moment.

Reed is a breathing app for iPhone that combines modern breathwork and classical pranayama. It measures how you feel before and after each session and shows you the shift in your own breath.

Yes. Every breathing session is free and unlimited, with no account required. An optional Reed Pro upgrade adds personal insights, the full wellbeing trend and custom patterns.

Ten sessions across two traditions. Breathwork: Box Breathing, 4-7-8 Calm, Coherence, Energize and Cyclic Sighing. Pranayama: Ujjayi, Nadi Shodhana, Kapalabhati, Bhramari and Bhastrika.

Instead of asking you to trust a feeling, Reed measures your state before and after and shows the change. A single orb guides the count, and it treats a shift of zero as an honest outcome. No wearable is required.

Reed's 4-7-8 Calm is built for the night: eight minutes with a long, slow exhale. In a small 2022 study in Physiological Reports, a few minutes of 4-7-8 breathing lowered heart rate and systolic blood pressure in 43 healthy young adults. The study didn't measure sleep, and Reed makes no promises about sleep.

Cyclic sighing, sometimes called the physiological sigh, is a slow double inhale through the nose followed by a long exhale through the mouth. It is one of Reed's ten sessions, and the pattern that performed best in a 2023 randomized Stanford study of daily five-minute breathing practices.

Nadi Shodhana, or Alternate Nostril breathing, is a classical pranayama technique that alternates the breath to balance and steady the mind. It is one of Reed's ten sessions.

Sessions range from about two to ten minutes.

Yes, with Reed Pro. Under Breathwork you can build your own ratio-based patterns, practise them like any other session, and pin up to two to your Home.

No. Reed works without an account or sign-up, and your sessions stay on your device.

For most people, gentle guided breathing is calming and safe. Some techniques are more intense, though, especially the faster, forceful ones like Kapalabhati and Bhastrika. Check with a doctor before you begin if you're pregnant, or have a heart condition, high or low blood pressure, a respiratory condition, epilepsy, or experience panic attacks. Always practise sitting or lying down somewhere safe, never while driving or in water, and stop if you feel dizzy or unwell. Reed shows this guidance in the app before your first session.

Many people reach for slow breathing to unwind or settle a busy mind, and Reed lets you see your own shift before and after. In a 2023 randomized Stanford study in Cell Reports Medicine, five minutes a day of cyclic sighing, the exhale-weighted pattern behind Reed's Cyclic Sighing session, improved mood and lowered breathing rate over a month. But Reed is for general wellbeing. It isn't medical advice or treatment, and isn't a substitute for care from a professional. If you're dealing with a health condition, your doctor is the right place to start.
