How to set a timer

  1. Pick a preset such as 5 or 10 minutes, or type hours, minutes and seconds.
  2. Press Start or the space bar. The time left also shows in the tab title, so you can switch to other tabs.
  3. When time is up the alarm rings until you press Stop alarm or the space bar, or for a minute. Choose the sound and volume under the buttons, and press Test sound to hear it first.

Quick timers

Use the presets for common lengths: 1 minute for a quick break or a plank, 3 minutes for a soft-boiled egg or tea, 5 and 10 minutes for short tasks and kids’ turns, 15 and 30 minutes for focused work, and 1 hour for longer study sessions or cooking.

Working in short blocks

A popular way to focus is the Pomodoro technique: 25 minutes of work, then a 5-minute break, with a longer break after four rounds. Type 25 minutes into the timer, start it, and work on one thing until the alarm rings.
