One bell to start, one to finish — a 20-minute sit with nothing to install and nothing to sign up for.
Twenty minutes is a solid, unhurried sit — the length many experienced practitioners settle into twice a day. It is long enough that the mind runs out of urgent business somewhere around minute eight.
A 20-minute sit benefits from the screen staying awake; on supporting browsers this timer holds a wake lock while you meditate, so a laptop sit does not dim halfway through.
Choose your bell and interval options above, press Begin, and close your eyes. The 20-minute timer starts immediately after a short preparation countdown, opens with one bell strike, and closes the sit when time is up. Keep the tab open — the timer keeps accurate time even in a background tab, and on laptops it can keep the screen awake while you sit.
Yes — every timer on this site is free, with no account and no ads on the timer itself. Your session history is stored only in your own browser.
Yes. The timer is anchored to the clock, not to the tab, so background tabs do not slow it down. Audio plays when the interval or closing bell fires.
You can choose a Tibetan bowl, a zen gong, or a soft chime, and add optional interval bells every 1–10 minutes. All sounds are synthesized in your browser — there are no audio files to download.
No account, no sync, nothing leaves your device. Export a backup anytime — it also works as a way to move your history to another browser.
