Pomodoro Study Timer
Run focus sprints, take short breaks, and earn a long break after every four pomodoros. Your daily focus log is saved privately on your device and the tab title always shows how much time is left.

Study Timer FAQ
How the timer rhythm works and where your focus data lives.
Where is my Pomodoro progress stored?
Completed focus sessions are saved locally in your browser's LocalStorage under the key suh-pomodoro-v1, grouped by date (e.g. 2026-08-13). The active timer session is kept under suh-pomodoro-session-v1 so a refresh never loses your run. Nothing is ever uploaded.
How do the break lengths work?
A standard Pomodoro rhythm is used: 25 minutes of focus, a 5-minute short break, and a 15-minute long break after every 4th completed focus session. When a session finishes you get a short beep and the timer automatically switches to the next mode.
Does the timer keep running if I switch tabs?
Yes. The countdown is computed from an absolute end timestamp rather than tick-by-tick subtraction, so even if the browser throttles timers in a background tab, the remaining time snaps back to the correct value the moment the tab is active again.
