How to use
Pick a pattern and a session length, then press Start. Breathe in while the circle grows, hold while it stays still, and breathe out while it shrinks. The text in the circle names each phase and counts down its seconds.
Box breathing uses four equal phases of 4 seconds. The 4-7-8 pattern breathes in for 4 seconds, holds for 7 and breathes out for 8. Coherent breathing goes in and out for 5.5 seconds each, a little under six breaths a minute.
Custom lets you set each phase from 0 to 20 seconds in half-second steps. Turn on tones to hear a soft cue at each phase change, so you can follow along with your eyes closed.
When your device is set to reduce motion, a progress bar replaces the circle. The session ends after the last full cycle. Stop at any time if you feel dizzy or short of breath.
FAQ
What is box breathing?
Box breathing is a pattern of four equal phases: breathe in, hold, breathe out and hold again, usually for 4 seconds each. The even count is easy to remember and to keep without a guide.
How do I do 4-7-8 breathing?
Breathe in quietly through your nose for 4 seconds, hold for 7, then breathe out through your mouth for 8. If the hold feels too long at first, use Custom to shorten every phase while keeping a similar ratio, and start with only a few cycles.
What is coherent breathing?
Coherent breathing, also called resonant breathing, slows your breathing to around five or six breaths a minute with an equal inhale and exhale. This tool uses 5.5 seconds for each half.
Can I follow along with my eyes closed?
Yes. Turn on tones: a rising tone marks breathing in, a falling tone marks breathing out, and a short steady tone marks each hold.
Is this a medical tool?
No. It is a timing guide for relaxed breathing practice. If you have a heart or lung condition, are pregnant, or feel unwell during breath holds, ask a doctor before practicing patterns with long holds.
