Focus Timer

It is a time-management method that alternates focused work intervals (classically 25 minutes) with short breaks, then a longer break after several rounds, to sustain concentration. The technique was invented by Francesco Cirillo and is based on the idea that frequent breaks improve mental agility and prevent fatigue. A typical session cycles through four 25-minute work intervals (called 'pomodoros') with 5-minute breaks between them, then a longer 15-30 minute break after completing all four rounds. This structured approach helps maintain focus by knowing a break is coming soon, and the rhythm prevents burnout through regular recovery periods.

Yes — you can enable an end-of-session alert so you know when to switch between work and break without watching the clock. The alert is a clear audio or visual notification that fires exactly when your work or break period completes, allowing you to set it and forget it rather than glancing at a timer constantly. This helps you stay fully focused on your task without distraction, knowing the alert will notify you when it's time to transition. You can customize the alert sound or type to suit your environment and preference.

Keep the tab open and the timer continues. For reliability, avoid letting your device sleep during a session, as your browser will pause when the computer goes to sleep. The timer runs in JavaScript in your browser tab, so switching to other tabs or applications won't stop it as long as your device remains active. If you need the timer to continue while you close the browser or let the device sleep, keep the tab open in your taskbar and take breaks without putting your device into sleep mode.
