Common interval protocols

Every one of these is a single round length that repeats, which is exactly what this timer does. Press a row and the round length and the round count are loaded and running.

Tabata · 20 s work / 10 s rest
HIIT, classic · 40 s work / 20 s rest
30/30 · 30 s work / 30 s rest
EMOM · one round on the minute
Sprint intervals · 30 s hard / 90 s easy
Little method · 60 s work / 75 s rest
How do I run repeated rounds?

Press the round length you want in the table below — Tabata, for instance, loads 20 seconds and eight rounds and starts straight away — or set the length by hand, tick Repeat and choose a count from the dropdown, ×2 up to ×10, or ×∞ to keep going until you stop. The badge under the digits shows which round you are on, for example ↻ 3/8.

Does it alternate work and rest by itself?

No. This repeats one fixed length, so a work/rest split like Tabata 20/10 cannot be run automatically in a single pass. Set the round to your work interval, repeat it, and time the rests with the pause button — which is what the round lengths above do for you.

What happens when the rounds run out?

The timer stops on its own and the alert plays, and the badge reads the final round. On ×∞ it keeps repeating until you press Stop, so the badge keeps climbing instead of finishing.

Does it keep counting if I close the tab?

No. The countdown and the round count live in this tab. Keep it open, and stop the screen from sleeping if you are mid-workout.
