Free Online Clock, Timer & Stopwatch — ScreenTimer.net

ScreenTimer is your all-in-one browser-based time tool. The moment you land on this page, you see your current local time displayed in a beautiful digital or analog clock — no app download, no sign-up, works on any device with a browser.

Online Clock

A clean, fullscreen digital clock showing your local time with date, 12/24-hour toggle, and seconds display. Switch to the analog view for a classic clock face with three style options: Classic, Minimal, and Roman numeral. Enable screensaver mode to use any device as a bedside or desk clock — the display drifts to prevent OLED burn-in.

Countdown Timer

Set hours, minutes, and seconds with intuitive up/down arrows or tap a quick preset. Choose from fifteen alarm sounds, enable last-10-second tick alerts, and optionally count up past zero so you know exactly how much overtime has elapsed. The countdown displays in your browser tab title — no need to switch tabs to check the time.

Online Stopwatch

Precise to the centisecond with unlimited lap recording. Every lap shows split time and cumulative total, with automatic highlighting of your fastest and slowest laps. Export your laps to CSV or copy them to your clipboard for training logs, reports, or analysis.

Pomodoro Timer

A built-in Pomodoro timer with configurable focus, short break, and long break durations. A circular progress ring tracks your session, dot indicators show how many pomodoros you have completed, and the timer auto-transitions between focus and break phases.

Multi Timer

Run unlimited parallel countdown timers simultaneously. Name each timer, set independent durations, and manage them all on one screen. Perfect for cooking multiple dishes, managing meeting agenda items, or timing workout circuits.

Alarm Clock

Set multiple alarms with custom labels, choose from fifteen unique synthesized tones, enable daily repeat, and snooze with one tap. All alarms persist across browser sessions. Preview any alarm sound before setting it.

World Clock

Search over 400 cities and timezones worldwide. Build your personal world clock board with live-updating cards showing local time, date, day/night indicator, and hour difference from your location. Your selections are saved automatically.

Customizable Preferences

Eight color themes from Midnight to Snow (light mode), fifteen alarm sound options, toggleable browser notifications, flash alerts, tab-title countdown, and full keyboard shortcut support. Every preference is saved and instantly applied.
