About the focus timer

The Focus Timer is a free Pomodoro-style timer designed to help you work in highly productive bursts and take regular breaks—without juggling multiple apps. Based on the famous Pomodoro Technique, this online timer encourages you to work in short, intense sessions and recharge with quick pauses so you can maintain energy and avoid burnout.

How the pomodoro-style focus timer works

  1. Set a 25-minute work session – The timer opens with the classic Pomodoro interval and a large digital countdown inside a circular progress ring.
  2. Press Start and stay on task – Watch the ring slowly unwind while you focus on your most important work.
  3. Take an automatic 5-minute break – When the timer hits zero, a gentle chime signals it’s time to rest. With auto-break enabled, the tool automatically loops work and break sessions, following the traditional Pomodoro rhythm.
  4. Customise your schedule – Edit the timer length for longer deep-work sprints or shorter bursts. The break period scales with your chosen session, or you can keep the standard 5-minute pause.
  5. Add time on the fly – Need to finish a thought? Tap +5 min to extend your session instantly.

  • Break big projects into manageable, motivating chunks.
