About this countdown timer

Set any duration from one minute up to several hours and count down with a clean, readable display. The timer keeps running even if you switch tabs, saves your session locally so it survives an accidental refresh, and lets you choose a silent, gentle, or strong finish alert. Add or subtract a minute while it runs, repeat the countdown automatically, keep supported screens awake, or open only the timer in full screen.

A countdown creates a clear finish line, which makes time feel tangible. Instead of drifting between tasks, you commit to a defined block and stop when the bell rings. Read ouropen timer-accuracy methodology to see how background timing and refresh recovery are tested.

Tips for using a countdown

  • Set a subject label so your session log shows what you worked on.
  • Use a 5-minute countdown for breaks so you stop scrolling on time.
  • Compare planned and actual time so your future estimates become more realistic.
  • Press Space to start or pause, R to reset, and F for the isolated full-screen timer.
  • Try the 25-minute Pomodoro preset if you are not sure where to start.

Where this timer works

  • Cooking and baking, when you need an honest reminder while your hands are busy.
  • Meetings and presentations, using the dedicated meeting timer to keep each agenda item on schedule.
  • Workouts, to time sets and rest between exercises.
  • Study blocks, using a 45- or 60-minute countdown for longer sessions.

Choose a preset timer

Each preset opens with the promised duration and the right tool. Pomodoro pages include work/break cycles, while workout pages switch between work and rest automatically.
