Countdown Timer
Count down from any duration, save presets, run repeating intervals, and get alerts at the end.
Custom Countdown Timer with Presets, Repeat Mode, Sound, and Notifications
Set a duration, start the countdown, and keep your routine consistent with saved timers and quick controls.
The timer stays accurate using timestamps. If you switch tabs, the countdown still reflects real time passed.

Use presets for common timers like 5 min, 10 min, 25 min, or any routine you repeat often.

Presets are ideal for routines. Save a few common timers, then load them in one click instead of retyping the duration each time.
For important alarms, keep your device awake and consider also setting a system timer. Browsers may delay alerts during deep sleep.

History records only completed runs (when the timer reaches zero). If you stop early, it is not counted unless you save a snapshot.
