Alarms only ring while this tab is open and the device is awake, with the volume on. They are saved in this browser.
How to use
- Choose the alarm time, an optional label and a sound, then press "Add alarm".
- Press "Test sound" to make sure your volume is loud enough.
- Keep this tab open. The countdown under the clock shows when the next alarm will ring.
- When the alarm rings, press "Stop" or "Snooze 5 min". Use the switch to turn an alarm back on for its next time.
Examples
Power naps
Set an alarm 20 minutes ahead and rest without checking your phone.
Meetings and classes
Add labeled alarms a few minutes before each session on your work computer.
Medication reminders
Use labels like "Vitamins" so you know why the alarm rang.
Frequently asked questions
Will the alarm ring if I close the tab or my computer sleeps?
No. A web page can only play sound while it is open and the device is awake. Keep the tab open (it can be in the background) and turn off sleep mode if you need a long alarm.
Why does it ask me to click the page?
Browsers block sound until you interact with a page. One click or key press after opening the page is enough.
Are my alarms saved?
Yes, in this browser only (local storage), so they are still there when you come back. Nothing is sent to a server.
Does an alarm repeat every day?
Each alarm rings once and then switches off. Turn it back on to schedule it for the next time that clock time comes around.
