What a 1 hour timer is for
An hour is the unit almost every calendar is built from — the exam, the appointment, the roast, the block of work you have set aside and want to protect.
What people set it for
- An exam or timed practice paper
- A meeting or appointment block
- Roasting and long cooking
- An hour of protected, uninterrupted work
How this timer behaves
The countdown is stored as the moment it should finish, not as a number being decremented, so switching tabs or minimising the window cannot make it run late, and pausing and resuming is exact. Through the final minute the readout and its ring turn red and pulse, giving you a warning before the alert rather than only at it.
It does not start on its own. The alarm is generated in your browser, and browsers keep audio silent until you interact with the page — so a timer that started by itself would be a timer that finished in silence. One tap on start is what makes the sound work.
