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.
