About ScreenTimer
ScreenTimer is a free, browser-based suite of time management tools built for speed, simplicity, and privacy. We believe the best tools are the ones that get out of your way — no sign-ups, no app downloads, no tracking. Open your browser, use the tool, close the tab. That is it.
What We Offer
ScreenTimer includes seven integrated tools in one lightweight application: an online clock with digital and analog displays, a precision stopwatch with lap recording and CSV export, a countdown timer with fifteen alarm sounds and deep-link presets, a Pomodoro timer with configurable intervals and automatic phase transitions, a multi-timer for running parallel countdowns, an alarm clock with snooze and daily repeat, and a world clock supporting over 400 cities and timezones.
Built for Everyone
Students timing exams. Teachers managing classroom transitions. Athletes tracking intervals. Home cooks juggling multiple dishes. Professionals blocking focused work sessions. Remote teams coordinating across timezones. Whatever your timing need, ScreenTimer handles it without installing anything.
Privacy First
ScreenTimer does not collect personal data. We do not require accounts, passwords, or email addresses. Your preferences, alarms, and world clock cities are stored locally on your device using your browser’s localStorage — they never leave your machine. We use Google AdSense to keep the service free, and that is the extent of third-party services on this site.
Technical Details
ScreenTimer is a pure client-side application. All timers, clocks, and alarms run in your browser using JavaScript’s high-resolution timing APIs. Alarm sounds are synthesized in real time using the Web Audio API — no audio files are downloaded. The application works offline once loaded (though you need an internet connection for the initial page load). It is tested across Chrome, Firefox, Safari, and Edge on desktop, tablet, and mobile devices.
