What does the circle show?

The circle grows while you breathe in, stays large during a hold, shrinks while you breathe out and stays small during the hold after it. The word in the middle says what to do and the number counts the seconds left in that phase.

Which breathing patterns are included?

"Box 4-4-4-4" is 4 seconds in, hold 4, out 4, hold 4. "4-7-8" is 4 seconds in, hold 7, out 8. "Coherent 5.5" is 5.5 seconds in and 5.5 out with no holds, about 5.5 breaths a minute. "Custom" lets you set each of the four timings from 0 to 30 seconds, with at least 1 second for breathing in and out.

How long is a session?

Choose 1, 2, 5, 10 or 15 minutes. The time left and the number of breaths done are shown while it runs, and the session ends by itself. Press "Stop" at any time to end it early.

Is this medical advice?

No. It is a simple pacing aid for relaxation. It does not diagnose or treat anything. If you feel dizzy, light-headed or unwell, stop and breathe normally, and ask a doctor first if you have a heart or lung condition or are unsure.

Can I add a sound, and are my choices saved?

Tick "Soft tone on each change" for a quiet tone at the start of each phase, with a different pitch for breathing in, holding and breathing out. It is off by default. Your pattern, custom timings, session length and tone choice are saved in this browser only, never in the page address.

Does it work on mobile?

Yes. It runs in current mobile browsers on iOS and Android, with nothing to install.
