Interval Timer – Tabata & HIIT with Cues
4:00
Ready
Your screen may turn off — keep it awake.
Keys: Space start/pause, R reset, + / − one minute, F focus. Shortcuts work when the timer is focused.
Set how long each work and rest phase lasts, how many rounds to run and a short prep countdown, then press Start. You hear three short blips before every change, a tone when work or rest begins and a final tone at the end. The current phase and round show on the card and in the tab title, so you can glance at it mid-set. It suits Tabata, HIIT circuits and EMOM workouts.
Ways to use the interval timer
- Tabata: 20 s work, 10 s rest, 8 rounds (the default).
- HIIT circuits with longer work blocks, such as 45 s on and 15 s off.
- EMOM sessions: 60 s work, 0 s rest, one round per minute.
- Stretching or plank holds with a short reset between sets.
How to set up an interval workout
- Enter the work and rest lengths in seconds, the number of rounds and the prep time.
- Press Start (or Space). Prep counts down first, then round 1 begins.
- Pause any time; the schedule continues from the same point when you resume.
- Bookmark or share the page address: it keeps your settings, for example ?w=45&r=15&n=10.
There is no rest after the last round, so a Tabata session lasts 10 s prep plus 8 × 20 s work and 7 × 10 s rest: 4 minutes.
