Which sound is the loudest for heavy sleepers?

Classic alarm is the most noticeable option for deep sleepers or noisy rooms. Beep is sharp for daytime reminders, while Soft chime is better for quiet spaces.

Will the alarm ring if my computer goes to sleep?

No. The alarm runs inside your browser tab, so your computer must stay awake and the tab must remain open for the sound to play.

Can I use my phone with a loud online alarm?

Phones pause browser tabs when the screen locks or the app moves to the background. For waking up on a phone, use your phone's built-in clock app instead.

Or ring in:

The alarm rings in this tab. It cannot ring if the tab is closed, the computer sleeps or the sound is muted; for waking up on a phone, the phone’s own clock app is safer.

Step by step

Connect external speakers or turn your device volume to maximum before opening the tool.
Select Classic alarm in the Sound menu, as its continuous tone cuts through background noise better than Soft chime.
Press Test sound to verify the volume in your room, then adjust your system or speaker knob if needed.
Choose your alarm time, add an optional label, and press Set alarm.
Keep the browser tab open and disable computer sleep mode so the alarm rings on time.
