Feel the rhythm

In the apps, Breathing taps the beat on your skin: a firm tap at every change of phase and lighter taps on the seconds in between. Close your eyes, hold the phone in your hand or rest it on your chest, and follow the rhythm without looking.

With sound on, the session continues while the screen is locked; on iPhone the vibration then switches to simple system pulses and returns to its fine-grained patterns after unlocking.

Browsers allow little or no vibration — none at all on iPhone, and on Android only coarse on/off patterns that stop once the screen locks. That is why the web version cannot make the rhythm felt. It is a technical limit, not a choice on our part: the apps use your device’s own haptic engine.

Try the rhythm in your browser; feel it in the app.

What Breathing is

Breathing offers simple guided breathing exercises: follow the circle as it grows and shrinks, and choose a pace that feels comfortable.

Box breathing, 4-7-8, coherent breathing and the physiological sigh are all included, each with cited references inside the app.

A session never starts on its own — you tap when you are ready.

How the app works

What research shows

Across many studies, slow breathing (under ~10 breaths/min) is associated with higher heart-rate variability, relaxation and reduced arousal, though individual responses vary (Zaccaro 2018; Russo 2017).
A remote, open-label randomized study assigned 108 participants to one of four groups; each protocol called for five minutes of daily practice for 28 days. Cyclic sighing increased positive affect more than mindfulness and reduced resting respiratory rate; it did not test a three-sigh demo (Balban 2023).

Breathing is not a treatment and promises no result. This information is educational and not medical advice. If you have cardiopulmonary or other medical conditions, consult a healthcare professional before changing your breathing practices.

Four techniques

Each page explains the technique, the evidence and how to practise it.

Box breathing (4-4-4-4)Four equal phases — inhale, hold, exhale, hold.Coherent breathingEqual inhale and exhale, no holds, around five to six breaths per minute — the cadence where heart and breath fall into step.4-7-8 breathingInhale for 4, hold for 7, exhale for 8.The physiological sighTwo quick inhales, one long exhale.

Private by design

No account, no ads, no tracking, no analytics.

The iOS app makes no network connections, and the Android app does not even hold the internet permission. The web version loads nothing from outside: no CDNs, no fonts, no analytics.
