Tabata is a fixed pattern: 20 seconds of work, 10 seconds of rest, eight times through. Eight work intervals and seven rests — four minutes once the ten-second countdown at the front is counted in. The numbers do not move; the shape is what the name refers to.
This page opens with those numbers already set, so the start is not a scramble. Change any of them and the link in the address bar changes with them.

How a run goes
Press start. A ten-second countdown runs before the first work interval.
Work for 20 seconds. The timer announces the change and counts the interval down.
Rest for 10 seconds. A rest follows every work interval except the last one.
Eight intervals in all. The strip above the clock shows how many are left.

Start
Beeps and a spoken “Go” before every work block tell you what's next. The colour shows what's on: green for work, blue for rest.

All templates at a glance.
All times include ten seconds to get ready.
Good to know.
The screen stays on.
While the timer runs, your screen won't turn off. If your browser can't do that, the timer tells you.
Landscape for distance.
Turn your phone and the timer shows only the time and what's on, big enough for the other side of the room.
Every setting is in the link.
Copy the address, send it, done. No account on either side.
Counted against the clock.
Put the phone down or switch tabs and the time is still right when you come back. The browser does pause the beeps in between, though.
