Online Timer & Stopwatch
A free online countdown timer and stopwatch with laps and an end-of-time chime. No sign-up.
About this tool
A simple, free online timer and stopwatch in one. Set a countdown for cooking, workouts, exams, or meetings and get a chime when time's up — or switch to the stopwatch to time how long something takes, with laps.
Countdown timer
Enter hours, minutes, and seconds, then press start. The timer counts down and rings a chime at zero. Pause and resume any time, or reset to set a new duration. Great for a 5-minute timer, a tea timer, an interval, or a presentation limit.
Stopwatch
The stopwatch counts up in minutes, seconds, and hundredths. Start and pause to accumulate time, hit Lap to record split times, and reset when you're done — useful for timing workouts, study sessions, or any activity.
How it works
Everything runs in your browser with no account. The stopwatch measures elapsed time from your device's clock for accuracy, and the countdown rings a tone generated in-browser. Keep the tab open while timing, as some browsers throttle timers in background tabs. For focused work sessions with automatic breaks, try the Pomodoro Timer.
Frequently asked questions
How do I set an online timer?
Enter the hours, minutes, and seconds you want on the Countdown tab and press Start. A chime sounds when it reaches zero.
What is the difference between the timer and the stopwatch?
The countdown timer counts down from a set time and alerts you when it ends. The stopwatch counts up from zero to measure how long something takes, with optional lap times.
Will it make a sound when the countdown ends?
Yes, a short chime plays at zero, generated in your browser. Keep the tab open so it can ring.
Does the timer keep running in a background tab?
It keeps running, but some browsers slow timers in background tabs, which can affect accuracy. Keep the tab visible for best results.
Do I need to install anything?
No. The timer and stopwatch run entirely in your browser with no account or download.
