About the Online Alarm Clock

Set an alarm for any time and this clock will ring in your browser when it arrives. A large live clock shows the current time so you always know how long is left.

It is handy as a reminder while you work, a nap timer, or a simple alarm on a device without one. Keep the tab open and it will sound at the set time.

Everything runs on your device with nothing uploaded.

Frequently asked questions

Will it ring if the tab is in the background?
It rings as long as the tab is open. For sound, make sure you have clicked on the page first, as browsers require an interaction before playing audio.
Does it work if my computer sleeps?
No. The device and browser need to stay awake for the alarm to fire at the set time.
Why did I not hear the alarm?
The tab must remain open and the browser must allow audio. Muted devices, sleep mode and suspended tabs can prevent the sound.
