How to play
- Pick a mode: Countdown, Stopwatch, or Count-up.
- For a countdown, set minutes and seconds and press Start (or spacebar).
- Use Fullscreen for a wall display; laps are one tap in Stopwatch mode.
- An alarm sounds at zero, with warning beeps in the last 5 seconds.
Three timers in one: a countdown with a progress ring, an end-of-time alarm and beeps for the last five seconds; a stopwatch with lap times; and a simple count-up clock. Go fullscreen for the classroom or the gym, and start/stop with the spacebar. Runs entirely in your browser — it keeps working offline once loaded.
Frequently asked questions
- Will the alarm sound if my phone is on silent?
- The timer plays its alarm through the browser, which respects your device volume — if the device is muted, raise the volume or watch the color change and progress ring instead.
- Can I use it fullscreen for a classroom?
- Yes — the fullscreen button turns the timer into a large wall display, and the spacebar starts and stops it without touching the mouse.
- Does the stopwatch support laps?
- Yes. In Stopwatch mode each Lap press records a split time in a list below the clock, so you can time repeated intervals.
