Optional breathing pace
Use an expanding and contracting visual cue to pace inhale, hold, and exhale phases. Choose a pattern and duration, pause at any time, and stop if the pace feels uncomfortable.
Follow the visible inhale, hold, and exhale timing at a comfortable pace.

This is a simple relaxation and focus preparation tool, not medical advice or treatment.
The page provides timing cues only. It does not sense breathing, oxygen, stress, or focus, and completion is not a health measurement.
Box breathing includes holds, while 4–6 and 3–3 alternate inhale and exhale. Use normal comfortable breaths; do not force depth or duration.
Box uses four equal phases: inhale, hold, exhale, hold. Calm uses a four-second inhale and six-second exhale. Quick reset uses equal three-second inhale and exhale phases.
These labels describe the interface presets and do not claim a clinical effect. Select another pace or stop if breath holding or timing causes discomfort.
Start initializes the chosen total duration. Pause stops phase progress, and reset returns the remaining time. Sound is an optional cue and should not be relied on as a safety alert.
Stop if you feel dizzy, short of breath, faint, or otherwise unwell. This general pacing tool is not medical advice, therapy, respiratory training, or an emergency resource.
The page keeps its basic controls and completed count in the current browser. It does not record microphone, camera, or physiological data.
These questions stay tied to the visible content on this page.
