Six stations of 45 seconds, 15 seconds to move between them, and the whole circuit run three times with a full minute between rounds. Stations sit inside a round, rounds sit inside the session — that nesting is what makes a circuit a circuit.
The phase strip shows which round you are in and which station is next, so the timer answers "where am I" without anybody counting. A ten-second countdown runs before the first station.
How a run goes
- Press start. A ten-second countdown runs before the first station.
- 45 seconds per station. The timer announces each station as it begins.
- 15 seconds to move on. The short rest is the changeover between stations.
- Three rounds of six. A full minute of rest separates one round from the next.
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.
