Runs in your browser. Nothing you type is sent anywhere.
No alarm set
Keep this tab open and your computer awake: the alarm can't ring from a closed tab or a sleeping laptop. On iPhone and iPad, keep this page on screen, because Safari pauses hidden tabs.
How to use the alarm clock
- Choose the alarm time, and add a label if you like.
- Press Set alarm. The page shows how long until it rings.
- Keep this tab open and your computer awake.
- When it rings, press Stop, or Snooze for 9 more minutes.
Questions
Does the alarm ring if I close the tab or my laptop sleeps?
No. The alarm lives in this page, so the tab must stay open and the computer must stay awake. The page keeps the screen on while an alarm is set, in browsers that support it. On iPhone and iPad, keep the page on screen, because Safari pauses hidden tabs.
Will it ring if the tab is in the background?
Yes, on computers. The sound is scheduled ahead with your browser's audio clock when you set the alarm, so it rings on time even while you work in another tab. Make sure your volume is up and the tab isn't muted.
What if the time has already passed today?
The alarm rings at that time tomorrow. The page always shows how long until it rings, so you can check.
Does it remember my alarm if I reload?
No. Browsers only play sound after you press something, so a reloaded page can't ring on its own. Set the alarm again after a reload.
What keyboard shortcuts are there?
When it rings, Space stops it and S snoozes for 9 minutes. F goes full screen.
Is anything sent to a server?
No. The alarm runs in your browser. Nothing you type is sent anywhere.
