What it does
Online Clock combines four time tools into one: a live digital clock, a wake-up alarm, a countdown timer with audible alert, and a millisecond-precision stopwatch with laps.
When to use it
Use it for cooking timers, workout intervals, presentations, study sessions (Pomodoro), kid bedtimes or whenever you need a quick alarm without installing an app.
Benefits
- 4 tools in one — clock, alarm, timer, stopwatch
- Audible beep on alarm and timer
- Lap times in stopwatch mode
- Works offline once loaded
Example
Set a 25-minute timer for a Pomodoro session, then switch to stopwatch to track a deeper task — no installs, no accounts.
Frequently asked questions
- Will the alarm ring if I close the tab?
- No — the alarm requires the tab to stay open. Keep this page in a pinned tab for it to fire.
- Does the stopwatch survive page reloads?
- No — for accuracy it runs in memory. Keep the tab open while timing.
- Can I set multiple alarms?
- Currently one alarm at a time. For more, open the page in multiple tabs.
