Meditation Timer

A minimalist meditation timer that runs entirely in your browser, with no app to install and no account to create. It counts down from your chosen duration with a large monospaced clock and, optionally, rings a soft 528 Hz sine-wave bell at each interval and again when the session ends. The bell is generated on the fly with the Web Audio API — there is no audio file to download.

Timing uses <code>performance.now()</code>, so the countdown does not drift if your system clock changes, and Pause/Resume preserve the accumulated elapsed time. The timer is timezone-independent: it works entirely in elapsed seconds.

Worked example: set duration to 10 minutes, interval to 2 minutes, and leave the bell ticked. The display starts at 10:00 and counts down. At 8:00, 6:00, 4:00, and 2:00 the bell rings softly to mark the interval boundary, and a final bell plays when the display reaches 00:00. The bottom of the panel shows which interval you are on (for example, "Interval 3 / 5"). Press Pause to freeze; the next session minute does not start until you press Resume.

If your browser blocks autoplay or you have audio disabled, the timer still works — it simply does not ring. Useful for daily practice, breathing exercises, focus blocks, or yoga rest periods.
