Free Online Stopwatch & Timer
A free stopwatch and countdown timer runs entirely in your browser. Use the stopwatch with Start, Pause, Reset, and lap times, or set hours, minutes, and seconds on the timer and get an audible alert when it reaches zero — no signup needed.
Switch between a stopwatch and a countdown timer in one tool. The stopwatch tracks elapsed time with lap recording using Date.now() for accuracy. The timer lets you set hours, minutes, and seconds, then plays a Web Audio beep when time is up. Free, no signup, fully client-side.

Frequently Asked Questions
- Is this stopwatch and timer free to use?
- Yes, completely free. No signup, no login, no payment ever.
- Do I need to create an account?
- No account needed. Open the tool and start timing immediately.
- Is my data safe?
- Everything runs in your browser. Nothing is uploaded to our servers.
- Why didn't I hear the timer alert?
- Browsers require a user gesture before playing audio. Press Start on the timer first — the beep plays when the countdown finishes after that.
- How accurate is the timing?
- We use Date.now() with periodic updates instead of counting ticks, which keeps drift low even if the browser tab is briefly busy.
