Timer, Stopwatch & Pomodoro
A countdown timer, a stopwatch with laps, and a Pomodoro focus cycle with a beep and optional desktop alert — 100% in your browser, no upload.
🔒 Everything runs in your browser with a plain interval timer — no accounts, no uploads, and the tab keeps ticking offline.
Timer, stopwatch and Pomodoro
This is three time tools in one page: a countdown Timer, a Stopwatch with lap splits, and a Pomodoro focus timer. Set the timer with minutes and seconds, then Start, Pause and Reset it; when it reaches zero the tool plays a short beep and can show a desktop notification if you allow it. The Stopwatch counts up to hundredths of a second and lets you record laps, showing both the split for each lap and the running total. Everything uses a plain interval in your browser, so it keeps running while the tab is open — even offline.
How the Pomodoro cycle works
The Pomodoro technique alternates focused work with short breaks. Pick your focus length (25 minutes by default), a short break (5 minutes) and a long break (15 minutes). After each focus session the tool automatically lines up a short break, and after every fourth focus session it lines up the longer break instead, then returns to work. A running counter shows how many focus sessions you have completed. Because the phase math is deterministic, the same sequence of sessions always produces the same breaks.
Frequently asked questions
Does the timer keep running if I switch tabs?
The countdown is anchored to the real clock, so when you return it shows the correct remaining time. Background tabs are throttled by the browser, which can delay the finish beep by a moment, but the time itself stays accurate.
Why do I need to allow notifications?
Browsers only let a page show a desktop notification after you grant permission. Tick 'Notify when finished' and accept the prompt; if you decline, the beep still plays. Nothing is sent anywhere — the notification is created locally.
What is the 25/5 Pomodoro pattern?
A common setup is 25 minutes of focus followed by a 5 minute short break, with a longer 15 minute break after four focus sessions. You can change all three lengths to suit your own rhythm.
Is anything uploaded or saved?
No. The timer, stopwatch and Pomodoro cycle all run entirely in your browser with JavaScript. No account is needed and nothing you enter leaves your device.
