Pomodoro Timer

The Pomodoro Timer runs the classic Pomodoro Technique — alternating focused work sessions with short breaks, and a longer break every fourth session — with a live countdown, a completed-session counter, a sound, and an optional browser notification when each phase ends. Set your focus, short-break and long-break durations (25/5/15 minutes by default), click Start, and the timer automatically advances through the cycle without you needing to reset it manually between phases. If you're after a 25 minute timer or a general focus timer online, this is a pomodoro technique timer that handles the whole cycle for you.

The technique itself is simple but effective: work in short, defined bursts with a clear end point rather than an open-ended "work until tired" stretch, then take a real break before the next burst. This tool automates the bookkeeping — tracking which phase you're in, counting completed focus sessions, and triggering a long break after every fourth one — so you can focus on the work instead of watching the clock or remembering what comes next.

When a phase ends, the timer plays a short tone (generated live via the Web Audio API, no audio file to load) and, if you've granted permission, shows a browser notification — useful if you've switched to another tab or app and want to know the moment a session ends without staring at the timer. You can pause and resume at any point, skip a phase early if you need to, or reset the whole cycle back to the start.

Everything runs locally in your browser — your focus-session count and durations are the only things saved (in this browser only, so they carry over between visits on this device), and nothing about your sessions is ever sent anywhere.
