Online Timer
A flexible countdown timer for workouts, cooking, focus sessions, meetings, and everyday tasks.
Free Online Countdown Timer
This timer is built for more than school use. Run short intervals for workouts, set focused work blocks, track cooking windows, or keep meetings on schedule. It works on desktop and mobile with no sign-up, no install, and no data collection.
How This Timer Stays Accurate
Instead of subtracting one second at a time, the timer stores an absolute end time and recalculates remaining time on every tick. That means it remains accurate if your tab is inactive, your device is busy, or your browser throttles background intervals.
Use Loop Mode for Repeating Intervals
Enable Loop mode to restart the countdown automatically each time it reaches zero. This is useful for interval training, repeating stretch breaks, and recurring focus/rest cycles where you want the timer to continue until you stop it.
Fullscreen and Keyboard Shortcuts
Use Fullscreen for wall displays, meetings, or group sessions. Keyboard shortcuts make quick control easy: Space starts or pauses, R resets, and F toggles fullscreen.
