Sound and extras
End sound

Synthesized in the browser — a decaying chime or bell, not a beep. Soft chime is the gentlest.

Off unless you want a soft mark during a longer sit. It will not ring at the same moment as the close.

Stays moderate. Your device volume still applies.

How to use it

Pick a length, sit, and let the close come to you. Start is silent unless you ask for a very soft opening chime. The default end sound is the gentlest of the three: a small decaying bowl. Wind chimes and distant bells are the same idea, a little brighter or lower. Silent close is there for a shared room, a sleeping house, or a sit where even a chime would be too much.

A gentle interval bell is off unless you turn it on. Use it for a longer sit if you want a quiet mark every so many minutes — still a chime, not a slap. Open sit mode if you want the chrome to step back.

The screen and other tabs

While the timer runs, we ask the browser to keep the screen awake (wakeLock) if it knows how. That request can fail on some phones, in battery-saver modes, or if the page is not visible. If the screen still sleeps, the sitting is not lost; the remaining time is counted from the real clock.

Background tabs are less reliable. Some browsers slow scripts or mute audio when this page is not in front. We schedule the end sound on the audio clock when you press Start, which often still rings — but a phone or laptop may still swallow it. If the close matters, keep this tab open. When you return, the clock catches up, and you will see Session complete even if you heard nothing.

Keep your practice instructions nearby

The timer marks an ending; it does not choose a practice or establish readiness. Use the preparation and length appropriate to the activity you have chosen. The eight-limb reference explains the source framework, while the Meditation course provides a guided introduction beginning with a session plan.

When you are ready

Return to your chosen instructions before starting another session. You can also use the reference to look up a term or explore its sources.
