Timer & Stopwatch
A countdown timer with handy presets, plus a stopwatch with laps — for cooking, workouts, study and sports.
Countdown timer
Stopwatch
What is this tool?
A reliable timer and stopwatch cover a surprising share of daily life: a 25-minute Pomodoro study sprint, pasta that needs exactly 9 minutes, a plank challenge, classroom quizzes, baking, brewing coffee, and timing laps at track practice. This page combines both tools, with one-tap presets for the most common countdowns and lap timing on the stopwatch.
The timer counts down from any minutes-and-seconds combination and announces when time is up. The stopwatch counts up with hundredths of a second and records laps without stopping, so you can compare splits across a workout or a set of student presentations. Both run entirely in your browser tab — just keep the tab open while they run.
How to use it
- Timer: enter minutes and seconds (or tap a preset), then press Start.
- Stopwatch: press Start, use Lap to record splits, and Pause or Reset as needed.
- Keep this browser tab open while a timer runs.
Formula & method
Worked example
A student uses the 25-minute preset for a Pomodoro focus session, takes a 5-minute preset break, and repeats — a popular study rhythm. A coach uses the stopwatch laps to record each runner's 400-meter split during practice.
Frequently asked questions
Does the timer keep running if I switch tabs?
Yes, it keeps counting while the tab stays open, even in the background. Closing the tab stops it, and browsers may throttle very old background tabs, so keep it open for important timing.
What is a Pomodoro timer?
The Pomodoro Technique alternates 25 minutes of focused work with a 5-minute break. The presets on this page match that pattern exactly — 25 minutes for work, 5 for the break.
Can I time multiple laps or people?
Use the Lap button on the stopwatch: each press records a numbered split in the list while the main clock keeps running, which works for races, presentations and interval workouts.
