Interval Timer with Beep
This is a minimalist interval timer with beep — set a number of seconds or minutes above, tap Start Beeping, and a short synthesized tone plays on every interval until you stop it. There's no audio file to load and no drift over long sessions: the timing runs on a background clock built specifically to keep the beat exact even if you switch to another tab or lock your screen.
How the Interval Beeper Works
Enter a number in the interval field, choose Seconds or Minutes, and tap Start Beeping. The screen switches to a countdown showing the time until the next beep, with a full-screen color pulse flashing in sync each time the tone fires. Tap the large Stop button whenever you're done — there's nothing to save or configure beyond the interval itself.
Because the countdown runs in a background timer rather than the page's own clock, the beep keeps its exact cadence even while a phone screen is off or the browser tab is in the background — the point of a screen-free pacer is that you shouldn't need to keep looking at it.
Common Beep Intervals (10, 20, 30, and 60 Seconds, and 1 Minute)
Any whole number works, but a few lengths cover most uses: 10 seconds for fast tempo drills, 20 or 30 seconds for HIIT-style work rounds, and 60 seconds (1 minute) for a slower, steady pacing beat. Switch the unit toggle to Minutes for anything longer — a 2, 5, or 10-minute repeating beep is set up the same way, just with a bigger number and the other unit selected.
Adjusting Pitch and Volume
Tap Audio Settings on the setup screen to open two sliders: Tone Pitch, adjustable from 200 Hz to 2000 Hz, and Volume. A lower pitch reads as a duller thud and a higher one as a sharper chirp — useful for telling this timer's beep apart from a phone's other notification sounds. Both sliders apply live, including mid-session, so you can dial in the tone while the beeper is already running.
Uses for a Repeating Beep Timer
A single, exact, repeating beep is a simple tool with a wide range of uses: tempo training for running or rowing drills, marking HIIT or interval workout rounds, cueing a meditation or breathing practice without a screen to watch, pacing a public-speaking or presentation rehearsal, or any repetitive task that benefits from a strict, screen-free beat instead of glancing at a clock.
Frequently Asked Questions
How do I make a timer beep every 30 seconds?
Set the interval field to 30, keep the unit on Seconds, and tap Start Beeping. The timer plays a short synthesized beep every 30 seconds until you tap Stop — no downloads or audio files involved, just a tone generated live in your browser.
Can I set an interval timer to beep every minute?
Yes — switch the unit toggle to Minutes, set the interval to 1, and tap Start Beeping. Any whole number of minutes works the same way, so a 2, 5, or 10-minute repeating beep is just as easy to set up.
Is there a free online interval timer with a beep?
Yes — this interval timer is completely free, with no account, no sign-up, and no ads. It runs entirely in your browser, generating the beep tone itself rather than loading an audio file, so there's nothing to download and nothing to track you with.
Can I use a 10 second interval timer with beep for tempo training?
Yes. Set the interval to 10 seconds and Start Beeping, and it holds an exact, drift-free cadence for as long as you need — useful for tempo training, drill pacing, or any repetition that needs a strict, screen-free beat to move to.
Does this work as a HIIT interval timer?
Yes — set the beep to whatever round length your workout uses (30 seconds and 1 minute are common HIIT lengths) and each beep marks the next round or rest period. It's a plain repeating cue rather than a full work/rest timer with separate phases, so it suits styles where one beep is all you need to keep moving.
