Popular uses for online timers

The Pomodoro Technique

The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. It uses focused work intervals (traditionally 25 minutes) separated by short breaks (5 minutes). After four "pomodoros," you take a longer break of 15-30 minutes.

How to apply it with our online timer:

  1. Set the timer to 25 minutes
  2. Work with full focus until the alarm sounds
  3. Take a 5-minute break
