About Meditation Timer

A meditation timer that marks the beginning, middle, and end of a session with gentle bowl chimes instead of jarring alarms. Set a duration, press Start, and a soft tone sounds at the 25% mark, the 50% mark, the 75% mark, and the end — four chimes total. The chimes are synthesized in the browser via the Web Audio API, so there is no buffering and no looping seam.

Why Bowl Chimes?

A sudden alarm at the end of a meditation session jolts the nervous system out of the relaxed state you just spent twenty minutes building. A singing-bowl tone decays slowly over two or three seconds, giving the mind time to transition from deep focus to alert awareness. The four chimes at quarter-points let you track the session's progress without opening your eyes to check a clock.

Synthesized, Not Sampled

The chimes are generated live in the browser using a stack of detuned sine oscillators with exponential decay envelopes. This produces a tone that is close to a real Tibetan singing bowl without requiring a 40MB audio file. The synthesis is deterministic — every chime sounds the same, every time, with no buffering delay.

Frequently asked

The shortest path between you and the answer.

Can I mute the quarter-point chimes?

Not currently. The quarter-point markers are the core feature. If you want a single chime at the end only, use the countdown timer with the chime option enabled.

Is this tool free?

Yes. Every ScreenTools.co tool is free, with no account, no paywall, and no install.

Does it work on mobile?

Yes. Layouts adapt to phone and tablet screens. Mobile Safari restricts true fullscreen, but the page fills the viewport and you can add the page to your Home Screen for an app-like experience.

Does it work offline?

Once a tool's page has loaded once, the runtime is local. A few tools that fetch fonts or icons need the first hit online; after that, refresh works offline.

Does this collect my data?

No personal data leaves your browser. The site has lightweight, privacy-respecting analytics for aggregate counts (which tool was opened) and nothing else.
