The remaining time also shows in the browser tab, so you can switch away and still see it. Keep the tab unmuted for the alarm.
A timer runs the session. Whether the sessions happen most days is a different record: a free habit tracker that shows the whole month on one screen.
Track it as a habitBrowsers slow down pages you are not looking at. A timer that counts its own ticks drifts when you switch tabs, sometimes by minutes. This one stores the moment it should finish and works backwards from the clock, so switching away changes nothing. The remaining time also shows in the tab title.
The one thing a background tab can delay is the sound. If the alarm matters, keep the tab visible or at least unmuted.
The space bar starts and pauses. The plus button adds a minute, running or not. Full screen makes the clock readable across a room, which is what you want in a classroom or a kitchen.
Copy the link to share or bookmark a specific timer. A link ending in ?m=10 always opens a ten-minute timer, ready to start.
Presets run from 1 to 60 minutes.
The time also appears in the tab title.
It repeats for up to 30 seconds.
Yes. It works from the clock, not from counting ticks, so the time stays accurate in a background tab.
Browsers only allow sound after you have tapped the page, and a muted tab or device stays silent. Starting the timer with a tap or the space bar counts as that first tap.
Copy the link to these numbers. Opening it later sets the same time, ready to start.
