How to use the online timer
Tracking a 159 minutes shift with a running timer helps more than watching the clock, especially near the end when every minute seems to slow down. Start it when you clock on, glance over now and then to see where you're at, and leave the tab open in the background while you get on with the job. It won't make the shift shorter, just easier to pace.
There's nothing to configure beyond tapping the button: press Start and the numbers begin ticking down straight away. The tab needs to stay open in your browser for the whole stretch, since closing it or switching the computer off stops the count, though you're free to switch to another tab and come back later. A clear alarm sounds the moment it hits zero, loud enough to notice from another room.
Setting an egg timer or fumbling with a phone app both work, but neither is as quick as a browser tab you already have open. There's no app store, no update prompt, and no login screen between you and starting the count. It's free and needs no registration, it works on any device with a browser, and closing other tabs won't affect it as long as this one stays open. If you would rather say put a timer on for 159 minutes, that works too — press Start and the page does the rest.
Common questions
Do I need to install anything to use the timer?
No. It runs straight in your browser, so there's nothing to download and no account to create.
Will the timer keep running if I close the tab?
No. Closing the tab or the browser stops the countdown, so leave it open until the timer finishes.
Can I use the timer on my phone?
Yes. It works in any mobile browser, though the tab still needs to stay open rather than sitting behind other apps for a reliable count.
Does the timer make a sound when it finishes?
Yes, an alarm plays once it reaches zero, provided your device's volume is turned up and the tab hasn't been muted.
