Set an alarm for 10:00 AM
The clock above is already set to 10:00 AM. Press Start alarm and leave this tab open — it will ring at 10:00 AM even if you are working in another tab.
10:00 AM is a morning wake time, which means you are setting it the night before and you will be at your least conscious when it goes off. That is exactly the situation the maths challenge is built for.
Test the sound once so your browser unlocks audio, turn the volume up, and keep the device plugged in with sleep disabled. A browser alarm is only as reliable as the machine it runs on.

Questions about setting an alarm for 10:00 AM
How do I set an alarm for 10:00 AM?
This page is already set to 10:00 AM — press Start alarm and it is armed. If 10:00 AM has already passed today, the alarm is set for 10:00 AM tomorrow. Bookmark this page and the time will be pre-filled every time you come back.
How long until 10:00 AM?
Once you press start, the panel shows a live countdown and the browser tab title updates with the time remaining, so you can check it without switching back to this tab.
Will it work if I close the tab?
No. A web page stops running when its tab closes, when the browser quits, or when the device sleeps. Keep the tab open and the device awake, and set a second alarm if oversleeping would be a real problem.
