How to use the interval timer
- 1
Set the length of one interval — for example 30 seconds, or 3 minutes.
- 2
Choose how many times it should repeat, or let it loop until you stop it.
- 3
Press Start — the timer counts down one interval, signals, and immediately begins the next.
- 4
Each repeat is marked with a clear cue so you can act on the sound, not the screen.
- 5
Pause or reset at any time; the repeat counter shows how many intervals you have done.
Tips & tricks
A repeating interval timer is the simplest building block of timed practice: one length, looped. It suits drills, study blocks, stretching routines, language practice, posture reminders — anything you do in even chunks.
Because every interval ends with a cue, you can use it hands-free. Set it, put the device down, and respond to the sound each time it loops.
If you need different work and rest lengths, the HIIT and Tabata timers add that structure — but for a single repeating length, this is the fastest tool to set up.
Frequently asked questions
What is an interval timer used for?
It repeats a single interval length over and over with a cue each time — useful for drills, study blocks, stretching, practice sessions, or any routine done in even chunks.
Can it loop forever?
Yes. Set a fixed number of repeats, or let it loop continuously until you pause or reset it.
How is this different from the HIIT timer?
This timer repeats one length. The HIIT timer adds separate work and rest intervals, rounds and sets — use it when you need that structure.
Does it sound a cue on every repeat?
Yes, so you can use it hands-free and respond to the sound rather than watching the screen.
Does it keep time if I switch tabs?
Yes. The interval timer measures real elapsed time, so it stays accurate when the tab is in the background.
Is it free?
Yes — free, no sign-up, runs entirely in your browser.
