Online Timer
TimerStart lets you run a browser-based timer with quick presets, custom durations, sound controls, fullscreen mode, dim screen, and shareable timer links.
The tool application will be added in the next phase.
How to Use the Online Timer
When the page first loads, you'll notice the clock is already running; it is just counting elapsed time until you tell it otherwise. Click Set Timer and pick the duration you actually need. That is really the whole process.
Once it is counting down, you can pause it mid-way if something pulls your attention away, restart it from scratch, or stop it entirely and go back to the setup screen. If you want a specific sound, a certain volume, or the alarm to keep ringing until you deal with it, that is all tucked into the settings panel, the little gear icon, rather than cluttering up the main screen.
Quick Timers
Most of the time you do not need to think about it at all. You just need something running. That is what the Quick Timer buttons are for. Seconds, minutes, hours, pick one, click it, done.
The 5 Second Timer is about right for a countdown before a photo. The 20 Minute Timer covers a solid study block or a quick workout. The 2 Hour Timer is more of a let-the-dough-rise or settle-into-a-long-work-session duration. Whatever you are doing, there is a decent chance one of the presets already matches it.
When You Need Something More Specific
Presets do not cover everything, obviously. Say dinner needs exactly 1 hour, 25 minutes, and 30 seconds, not close to that, exactly that. Click Set Timer and build it out to the second instead of rounding to whatever is closest.
Pause, Restart, Stop
There are really just three things you can do once a timer is running. Pause stops the clock without losing your place; hit the same button again, now labeled Resume, and it picks right back up. Restart throws you back to the original duration and starts over. Stop ends it and drops you back at the setup screen.
Nothing complicated here, which is sort of the point.
Getting the Alarm Right
Open the gear icon and you will find five alarm sounds to choose from: Electric Oven Bell, Digital Clock Beep, Bright Success Twinkle, Red Alert Alarm, and Tropical Birds. Hit Test Sound before you commit, because nobody wants to find out what Red Alert Alarm sounds like for the first time when it is actually going off.
There is a volume slider too, and a Loop Alarm option if one beep is not going to cut it. Turn that on and it keeps sounding until you actually acknowledge it, instead of playing once and quietly giving up. Two more toggles, Show Progress and Show Expected End Time, are worth leaving on. The second one is genuinely useful; it tells you when the timer ends right on the screen, so you are not doing addition in your head.
Fullscreen, Dim Screen, and Sharing a Timer
Fullscreen does what you would expect: it blows the numbers up so you can read them from across the room, which matters more than you might think during a workout or a class. Press Esc when you are done with it.
Dim Screen is the opposite move: it darkens everything down while the countdown keeps running underneath, good for late at night or just cutting down on glare. There is an Exit Dim button when you want it back, and it will double-check you meant to click it.
One feature that is easy to miss: the link icon next to settings turns your current timer into a URL. Save that link, and reopening it brings the exact same countdown back: same duration, same end time. Useful if there is a timer you set up once and keep coming back to.
What People Actually Use This For
A student wants to study for 20 minutes before taking a break. They select the 20 Minute Timer and start immediately, nothing else to set up.
Someone cooking for an hour and ten minutes builds a custom timer using 1 Hour plus 10 Minutes, so the alarm goes off at exactly the right moment instead of guessing and checking the oven every few minutes anyway.
It is the same tool either way: studying, cooking, a workout, keeping a meeting from running long. You are just changing the numbers.
One Honest Caveat
This runs entirely in your browser, so the tab has to stay open for it to keep working. Close it, or shut the device down, and the countdown stops with it. There is no background process keeping track for you. Worth knowing if you are relying on it going off in another room.
Frequently Asked Questions
How do I set a timer online?
Click Set Timer, choose your duration, and start it. Or skip that entirely and use one of the Quick Timer presets if a common length works for you.
Can I set a timer for seconds, minutes, or hours?
Yes. Quick Timers cover all three, so you are one click away from a common duration without typing anything in.
Can I pause and resume it?
You can. Pause stops the clock, and the button becomes Resume. Tap it again and it continues from exactly where it left off, no time lost.
What happens when it hits zero?
Whatever alarm sound and volume you have set goes off. If Loop Alarm is turned on, it keeps going until you tell it to stop.
Can I change the sound?
Yes, from the settings panel: five sounds to pick from, plus a Test Sound button so you know what you are getting before it actually matters.
What does Loop Alarm do?
It means the alarm does not quit after one pass. It keeps sounding until you dismiss it, which is useful if you tend to miss the first alert.
Can I save a timer or send it to someone?
Yes. There is a link icon that turns your current timer into a shareable URL. Open that link later and you get the same timer back, duration and all.
Does it still run if I close the browser?
No. Close the tab and the countdown stops. It needs to stay open the whole time to keep counting and to ring when it is done.
