Tidy-up timer with a one-minute warning

The short answer
Three to five minutes is enough for most tidy-ups, with a one-minute warning before the end. The warning matters more than the total: stopping abruptly means a half-cleared table, and the shrinking ring on this timer gives a visual warning without you having to say anything.
Three steps to a timer on the wall
Step 1: Choose a time
Pick a preset or set your own. The timer remembers what you used last on this device.
Step 2: Press start
Start the timer, then press F or the fullscreen button to fill the screen.
Step 3: Run the room
Space pauses, the up arrow adds a minute, R resets. Fullscreen shows the timer alone, with no ads and no navigation.
Four things worth knowing
The one-minute warning is the whole trick
Stopping without warning leaves half-finished tables and unfinished sentences. The ring turns amber at 20% remaining, which on a five-minute countdown lands at one minute — say nothing and let the colour do it.
Use a calm chime, not a siren
An alarm in a quiet room startles people and turns the timer into something to dread. A soft chime, or just the colour change, achieves the same end.
The same length every time
Tidy-up gets faster when the class knows exactly how long it is. A duration that changes with your mood teaches them to wait and see.
Start it before you announce it
Press start, then speak. Announcing first and starting second gives away twenty seconds and undermines the point that the clock, not you, is running things.
No ads on your big screen
Ads pay for this page, and they stay on this page. The moment the timer goes fullscreen there is nothing on screen but the time — no banners, no navigation, no surprises in front of a room.

Questions people ask
Anything we've missed?
How long should tidy-up take?
Three to five minutes covers most classrooms, less for desks and books alone, more after a practical or art lesson. Keep it consistent — a predictable duration gets faster over a term.
Should I give a warning before time is up?
Yes, particularly for tidy-up and writing, where an abrupt stop means unfinished work. This timer turns amber at 20% remaining, which gives a visual warning without you interrupting.
Does it work in a nursery or reception class?
Yes, and the visual countdown matters more there than anywhere. Children who cannot yet read a clock can still see a ring getting smaller.
Can I use it without sound?
Yes. Mute the chime and the colour change alone carries the message, which is what you want in a room where a sudden noise would be disruptive.
