“Boil eggs for 7 minutes” or “practice the Pomodoro technique: 25 minutes of focus, 5 minute breaks” - these are moments when a timer or stopwatch helps.

In this article, we explain how to use a countdown timer and a stopwatch, covering setup, lap timing, and how to apply them to study and work.

Countdown timer vs stopwatch

Feature Use case Example
Countdown Manage a fixed amount of time 7-minute eggs, presentation timing
Stopwatch Measure elapsed time Running, tracking work hours

Both control time, but the choice depends on whether the duration is fixed in advance.

Key point: A timer answers "when does it end?", a stopwatch answers "how long did it take?". Pick the right tool for the goal.

Using the countdown timer

Setting 7 minutes for boiled eggs

  1. Enter 0 minutes and 7 seconds (or 0:07)
  2. Press start
  3. The remaining time is shown in large digits
  4. At zero, the screen flashes to alert you

Handy ways to use it

  • Pomodoro technique: alternate 25 minutes of focus with 5 minute breaks
  • Presentation timing: set your speaking time and watch the countdown
  • Interval training: repeat 30 seconds of exercise and 15 seconds of rest

Using the stopwatch

Lap timing example

  1. Switch to stopwatch mode
  2. Start and begin your activity
  3. Press the lap button at each split to record it
  4. Stop to finish, reset to start over

Up to 10 laps are recorded and listed, which helps with pace management during exercise or measuring each step of a task.
