Alarm Clock

Set a browser alarm and check its next occurrence

Choose once or selected weekdays

Set the hour, minute and AM/PM, then open Alarm options to add a label and choose a sound and volume. With no weekdays selected, the alarm is a one-time reminder. Select weekdays only when you want a repeating schedule. Read the Next preview before pressing Set alarm, especially near midnight or when setting the next minute.

Alarms use your device’s local time. If a one-time alarm’s time has already passed today, its next occurrence is on the following day. A repeating alarm uses the next selected weekday. Check your device’s date and time zone when a displayed next occurrence looks unexpected.

Prepare the browser for the reminder

Preview the selected tone, check the device volume, and allow notifications if you want them and your browser supports them. When the alert appears, Stop dismisses that occurrence and Snooze postpones it. Use the saved alarm’s On/Off control to change whether it is active.

An alarm can remain active while you move between OxClock pages. A closed browser, sleeping device, blocked audio or power-saving policy can prevent the alert from appearing or sounding. Keeping a page open improves availability but cannot guarantee delivery. Set a native device alarm as well for an essential reminder. For a duration such as ten minutes from now, a timer is easier than choosing a clock time.

Common questions

Does the alarm work on another OxClock page?

Yes, while the OxClock app remains active. Alarms persist and are watched globally.

Is it a replacement for my phone alarm?

No. Browsers and sleeping devices may suspend web activity, so critical alarms should also use a native clock app.
