How it works
About this 45 second timer
This is a ready-to-run 45 second timer. Press start and it counts down from 45 Second, then sounds an alarm and flashes the tab title so you notice from another window.
Press start to begin
The timer opens paused so it does not surprise you with a countdown. Press start when you are ready, or change the time first using the fields.
It works in the background
The countdown is anchored to a real clock, so it stays accurate even in a background tab. Leave it running while you work in another window.
