Slop Time · free, in your browser

Online stopwatch and countdown timer

Start, lap and reset a stopwatch that shows tenths of a second, or set a countdown in minutes, minutes and seconds, or hours. Both run in your browser tab.

Open the stopwatch

How to do it

1. Open Slop Time from this page: it starts on the Timers tab.
2. Press Start to run the stopwatch, Lap to record a lap and Reset to clear it. Each lap shows the total and its split.
3. For a countdown, type a length such as 5 (minutes), 4:30 or 1:05:00 and press Set, or pick 1, 5, 10 or 25 min.
4. Press Start. At zero you get a Timer done message, and the tab title starts with (Done).

Your files stay on this device: Slop Time runs in your browser, with no upload, no account and no watermark.

Questions

Does the countdown make a sound?

No. When the time is up the page shows a Timer done message and puts (Done) in the tab title, so you can see it from another tab. There is no alarm sound.

Does it keep time in a background tab?

Yes. Both are worked out from the clock rather than by counting ticks, so they stay right while the tab is in the background.

Is it saved if I reload the page?

No. The stopwatch and the countdown live in the page and reset when you reload or close it.

What can I type for the countdown?

A number is minutes (5), one colon is minutes and seconds (4:30), and two colons are hours, minutes and seconds (1:05:00).
