Timer & Stopwatch

A countdown timer and stopwatch in one clean window. Presets for 1, 3, 5 and 10 minutes, custom lengths, timestamp-accurate.

How to Use

1. Pick a mode at the top: Countdown or Stopwatch.
2. For a countdown, click a preset — 1, 3, 5 or 10 minutes — or type any number of minutes in the custom field.
3. Press Start. Pause and resume whenever you like; Reset clears everything.
4. When a countdown reaches zero the display turns red — keep the window where you can see it, since there's no sound.

About This Tool

Some timers live on your phone, some on your microwave — this one lives in a browser tab, which turns out to be exactly where office timing needs to happen. Steeping tea for three minutes, keeping a stand-up to ten, timing a presentation run-through, giving yourself "five more minutes" of a break that would otherwise stretch to twenty: an online timer covers all of it without you touching your phone. This one is two tools in a single window. Countdown mode counts a set duration down to zero — hit one of the presets (1, 3, 5 or 10 minutes) or type any number of minutes — while stopwatch mode counts up from zero for anything open-ended: how long the build takes, how long that "quick" call actually ran, your plank. Under the hood it does timekeeping the honest way. Naive web timers add up little one-second ticks, and each tick can land late, so the errors pile up. This timer records real timestamps instead and recomputes elapsed time from the clock every time it draws the display, so a 10-minute countdown ends 10 minutes after you press start — not 10 minutes plus drift. Pausing and resuming stays exact for the same reason. One honest caveat: browsers deliberately slow down background tabs to save power. The math stays right — switch back and the display snaps to the true remaining time — but while the tab is hidden, the screen refreshes lazily and the moment of hitting zero can slip past unnoticed. Since the timer is also silent by design (the display turns red at zero, but there's no chime), the practical advice is simple: keep it visible. That's easy here, because on BytePlay's Windows 98-style desktop the timer opens as a small draggable window you can park in a corner of the screen next to whatever you're doing. No download, no account, no permissions to grant — open it, press start, and go do whatever those three minutes are for.

Frequently Asked Questions

How do I set a timer for 5 minutes?

Make sure you're in Countdown mode, click the 5 min preset, then press Start. For any other length, type the number of minutes into the custom field — anything from 1 minute up — and it's applied immediately.

Does the timer keep running in a background tab?

The timekeeping itself stays correct, because elapsed time is computed from real timestamps rather than counted ticks. But browsers throttle hidden tabs, so the display refreshes lazily and the moment a countdown hits zero can pass silently. Keep the timer visible — for example as a small window on the BytePlay desktop.

What's the difference between the timer and the stopwatch?

The countdown starts from a duration you choose and runs down to zero — good for tea, breaks and time-boxed tasks. The stopwatch starts at zero and counts up until you stop it — good for measuring how long something takes. Both share the same Start, Pause and Reset controls.

Is there a sound when the timer ends?

Not currently — the timer is silent, and the display turns red when a countdown reaches zero. That's a deliberate office-friendly default, but it does mean you should keep the window where you can see it. An optional chime is on the wish list.
