About the Online Alarm Clock
An online alarm clock lets you set a specific time for an alert to go off. This free alarm clock shows a large live clock and lets you pick an alarm time and a label (like “Wake up” or “Meeting”). When your device clock reaches that time, an alarm sound plays and a notification appears until you dismiss it.
It is great as a wake-up alarm, a reminder for meetings, breaks, medication, the oven, laundry or any moment you need to be nudged. Keep the tab open, allow sound and notifications, and it does the rest. Everything runs on your device — nothing is uploaded — and your alarm setting is remembered.
