Three minutes of work, one minute of rest, twelve times through. The timer calls the start and the end of every round out loud, so the bell is not something anybody has to watch the clock for.

Twelve rounds runs a little over forty-seven minutes. Set the round count lower for a shorter session — every setting travels in the link, so one address sends the same session to a whole room.

How a run goes

1. Press start. A ten-second countdown runs before the first round.
2. Three minutes of work. The timer announces the round and counts it down.
3. One minute of rest. A rest phase follows every round except the last one.
4. Twelve rounds in all. Twelve work phases, eleven rests between them.

What this timer does

An interval timer counts work and rest for you so you can stop counting and start moving. Set how long you work, how long you rest, and how many times — the timer handles the rest, calls every change out loud, and shows the whole session as a strip so you always know what is coming.

Time here is measured against the clock, not counted down by a ticker. Put the phone down, pick it up again, and the timer is exactly where it should be rather than a few seconds behind. That sounds like a detail until you have done eight rounds against a timer that drifted.

Every setting travels in the link. Copy the address bar and you have shared your session — no account on either end.

One thing a browser cannot do

When your screen switches off, or you leave this tab, the browser stops the audio. The clock still comes out right when you return, but you will not have heard the beeps in between. We ask the browser to keep the screen awake where it can, and we tell you when it cannot — because a tool that names its limit is more useful than one that hides it.
