Repeat timer
Enter values, then press Calculate.
Repeats N times at the interval you set. Useful for workout or study intervals.
How to use
- In Interval (seconds), set the length of one round. The field ranges from 1 to 3600 seconds; the default is 30.
- In Repeat count, set how many rounds to run. Range 1–999; default 5.
- Leave Beep at the end of each round on to play a short sound when a round finishes. It is on by default.
- Press Start. Status becomes in progress, and Seconds left this round and Progress (current / total) update.
- Press Stop to pause, or Reset to clear remaining seconds and progress. After reset, status is idle.
- If interval or count is less than 1, status asks you to check interval and count. Fix the numbers and start again.
Key concepts
The repeat timer is an interval clock that runs the same second length N times. Unlike a one-shot timer alarm, remaining seconds refill when a new round starts. The progress field shows which round you are on.
The beep uses AudioContext at 660 Hz for a short tone. Audio is unlocked on the Start click, so keep the checkbox on and press Start if you want sound. Background tabs may delay round changes. Values live only in the browser. There is no separate rest-seconds field. For 40 seconds work and 20 seconds rest, run one set at 40 and another at 20, or use a stopwatch alongside.
Example
For five 30-second squats, set interval 30, repeat 5, turn the beep on, and start. Progress goes from 1 / 5 to 5 / 5, with a sound at the end of each round. When finished, status is complete and seconds left this round is 0. There is no separate rest-length control. For a 60-second English vocab timer × 10, use interval 60 and count 10. Watch the progress number rise as rounds advance.

Frequently asked questions
Can I set work and rest times separately on the repeat timer?
No. There is one interval and a repeat count. To time work and rest differently, split into two runs or use a stopwatch as well.
I cannot hear the repeat timer beep.
Start with Beep at the end of each round turned on so the browser allows audio. Autoplay policy can block sound before a click.
Does Stop reset the round on the repeat timer?
Stop only pauses. Press Reset to set the numbers back to 0. Starting again begins from round 1.
What is the maximum interval on the repeat timer?
The field maximum is 3600 seconds (1 hour). Count goes up to 999.
Should I use the timer alarm or the repeat timer?
Use the timer alarm for a single alert. Use the repeat timer to repeat the same number of seconds many times.
Are repeat timer sessions saved?
No. Closing the tab also clears the current round.
